### GNU AFFERO GENERAL PUBLIC LICENSE
 | 
			
		||||
 | 
			
		||||
Version 3, 19 November 2007
 | 
			
		||||
 | 
			
		||||
Copyright (C) 2007 Free Software Foundation, Inc.
 | 
			
		||||
<https://fsf.org/>
 | 
			
		||||
 | 
			
		||||
Everyone is permitted to copy and distribute verbatim copies of this
 | 
			
		||||
license document, but changing it is not allowed.
 | 
			
		||||
 | 
			
		||||
### Preamble
 | 
			
		||||
 | 
			
		||||
The GNU Affero General Public License is a free, copyleft license for
 | 
			
		||||
software and other kinds of works, specifically designed to ensure
 | 
			
		||||
cooperation with the community in the case of network server software.
 | 
			
		||||
 | 
			
		||||
The licenses for most software and other practical works are designed
 | 
			
		||||
to take away your freedom to share and change the works. By contrast,
 | 
			
		||||
our General Public Licenses are intended to guarantee your freedom to
 | 
			
		||||
share and change all versions of a program--to make sure it remains
 | 
			
		||||
free software for all its users.
 | 
			
		||||
 | 
			
		||||
When we speak of free software, we are referring to freedom, not
 | 
			
		||||
price. Our General Public Licenses are designed to make sure that you
 | 
			
		||||
have the freedom to distribute copies of free software (and charge for
 | 
			
		||||
them if you wish), that you receive source code or can get it if you
 | 
			
		||||
want it, that you can change the software or use pieces of it in new
 | 
			
		||||
free programs, and that you know you can do these things.
 | 
			
		||||
 | 
			
		||||
Developers that use our General Public Licenses protect your rights
 | 
			
		||||
with two steps: (1) assert copyright on the software, and (2) offer
 | 
			
		||||
you this License which gives you legal permission to copy, distribute
 | 
			
		||||
and/or modify the software.
 | 
			
		||||
 | 
			
		||||
A secondary benefit of defending all users' freedom is that
 | 
			
		||||
improvements made in alternate versions of the program, if they
 | 
			
		||||
receive widespread use, become available for other developers to
 | 
			
		||||
incorporate. Many developers of free software are heartened and
 | 
			
		||||
encouraged by the resulting cooperation. However, in the case of
 | 
			
		||||
software used on network servers, this result may fail to come about.
 | 
			
		||||
The GNU General Public License permits making a modified version and
 | 
			
		||||
letting the public access it on a server without ever releasing its
 | 
			
		||||
source code to the public.
 | 
			
		||||
 | 
			
		||||
The GNU Affero General Public License is designed specifically to
 | 
			
		||||
ensure that, in such cases, the modified source code becomes available
 | 
			
		||||
to the community. It requires the operator of a network server to
 | 
			
		||||
provide the source code of the modified version running there to the
 | 
			
		||||
users of that server. Therefore, public use of a modified version, on
 | 
			
		||||
a publicly accessible server, gives the public access to the source
 | 
			
		||||
code of the modified version.
 | 
			
		||||
 | 
			
		||||
An older license, called the Affero General Public License and
 | 
			
		||||
published by Affero, was designed to accomplish similar goals. This is
 | 
			
		||||
a different license, not a version of the Affero GPL, but Affero has
 | 
			
		||||
released a new version of the Affero GPL which permits relicensing
 | 
			
		||||
under this license.
 | 
			
		||||
 | 
			
		||||
The precise terms and conditions for copying, distribution and
 | 
			
		||||
modification follow.
 | 
			
		||||
 | 
			
		||||
### TERMS AND CONDITIONS
 | 
			
		||||
 | 
			
		||||
#### 0. Definitions.
 | 
			
		||||
 | 
			
		||||
"This License" refers to version 3 of the GNU Affero General Public
 | 
			
		||||
License.
 | 
			
		||||
 | 
			
		||||
"Copyright" also means copyright-like laws that apply to other kinds
 | 
			
		||||
of works, such as semiconductor masks.
 | 
			
		||||
 | 
			
		||||
"The Program" refers to any copyrightable work licensed under this
 | 
			
		||||
License. Each licensee is addressed as "you". "Licensees" and
 | 
			
		||||
"recipients" may be individuals or organizations.
 | 
			
		||||
 | 
			
		||||
To "modify" a work means to copy from or adapt all or part of the work
 | 
			
		||||
in a fashion requiring copyright permission, other than the making of
 | 
			
		||||
an exact copy. The resulting work is called a "modified version" of
 | 
			
		||||
the earlier work or a work "based on" the earlier work.
 | 
			
		||||
 | 
			
		||||
A "covered work" means either the unmodified Program or a work based
 | 
			
		||||
on the Program.
 | 
			
		||||
 | 
			
		||||
To "propagate" a work means to do anything with it that, without
 | 
			
		||||
permission, would make you directly or secondarily liable for
 | 
			
		||||
infringement under applicable copyright law, except executing it on a
 | 
			
		||||
computer or modifying a private copy. Propagation includes copying,
 | 
			
		||||
distribution (with or without modification), making available to the
 | 
			
		||||
public, and in some countries other activities as well.
 | 
			
		||||
 | 
			
		||||
To "convey" a work means any kind of propagation that enables other
 | 
			
		||||
parties to make or receive copies. Mere interaction with a user
 | 
			
		||||
through a computer network, with no transfer of a copy, is not
 | 
			
		||||
conveying.
 | 
			
		||||
 | 
			
		||||
An interactive user interface displays "Appropriate Legal Notices" to
 | 
			
		||||
the extent that it includes a convenient and prominently visible
 | 
			
		||||
feature that (1) displays an appropriate copyright notice, and (2)
 | 
			
		||||
tells the user that there is no warranty for the work (except to the
 | 
			
		||||
extent that warranties are provided), that licensees may convey the
 | 
			
		||||
work under this License, and how to view a copy of this License. If
 | 
			
		||||
the interface presents a list of user commands or options, such as a
 | 
			
		||||
menu, a prominent item in the list meets this criterion.
 | 
			
		||||
 | 
			
		||||
#### 1. Source Code.
 | 
			
		||||
 | 
			
		||||
The "source code" for a work means the preferred form of the work for
 | 
			
		||||
making modifications to it. "Object code" means any non-source form of
 | 
			
		||||
a work.
 | 
			
		||||
 | 
			
		||||
A "Standard Interface" means an interface that either is an official
 | 
			
		||||
standard defined by a recognized standards body, or, in the case of
 | 
			
		||||
interfaces specified for a particular programming language, one that
 | 
			
		||||
is widely used among developers working in that language.
 | 
			
		||||
 | 
			
		||||
The "System Libraries" of an executable work include anything, other
 | 
			
		||||
than the work as a whole, that (a) is included in the normal form of
 | 
			
		||||
packaging a Major Component, but which is not part of that Major
 | 
			
		||||
Component, and (b) serves only to enable use of the work with that
 | 
			
		||||
Major Component, or to implement a Standard Interface for which an
 | 
			
		||||
implementation is available to the public in source code form. A
 | 
			
		||||
"Major Component", in this context, means a major essential component
 | 
			
		||||
(kernel, window system, and so on) of the specific operating system
 | 
			
		||||
(if any) on which the executable work runs, or a compiler used to
 | 
			
		||||
produce the work, or an object code interpreter used to run it.
 | 
			
		||||
 | 
			
		||||
The "Corresponding Source" for a work in object code form means all
 | 
			
		||||
the source code needed to generate, install, and (for an executable
 | 
			
		||||
work) run the object code and to modify the work, including scripts to
 | 
			
		||||
control those activities. However, it does not include the work's
 | 
			
		||||
System Libraries, or general-purpose tools or generally available free
 | 
			
		||||
programs which are used unmodified in performing those activities but
 | 
			
		||||
which are not part of the work. For example, Corresponding Source
 | 
			
		||||
includes interface definition files associated with source files for
 | 
			
		||||
the work, and the source code for shared libraries and dynamically
 | 
			
		||||
linked subprograms that the work is specifically designed to require,
 | 
			
		||||
such as by intimate data communication or control flow between those
 | 
			
		||||
subprograms and other parts of the work.
 | 
			
		||||
 | 
			
		||||
The Corresponding Source need not include anything that users can
 | 
			
		||||
regenerate automatically from other parts of the Corresponding Source.
 | 
			
		||||
 | 
			
		||||
The Corresponding Source for a work in source code form is that same
 | 
			
		||||
work.
 | 
			
		||||
 | 
			
		||||
#### 2. Basic Permissions.
 | 
			
		||||
 | 
			
		||||
All rights granted under this License are granted for the term of
 | 
			
		||||
copyright on the Program, and are irrevocable provided the stated
 | 
			
		||||
conditions are met. This License explicitly affirms your unlimited
 | 
			
		||||
permission to run the unmodified Program. The output from running a
 | 
			
		||||
covered work is covered by this License only if the output, given its
 | 
			
		||||
content, constitutes a covered work. This License acknowledges your
 | 
			
		||||
rights of fair use or other equivalent, as provided by copyright law.
 | 
			
		||||
 | 
			
		||||
You may make, run and propagate covered works that you do not convey,
 | 
			
		||||
without conditions so long as your license otherwise remains in force.
 | 
			
		||||
You may convey covered works to others for the sole purpose of having
 | 
			
		||||
them make modifications exclusively for you, or provide you with
 | 
			
		||||
facilities for running those works, provided that you comply with the
 | 
			
		||||
terms of this License in conveying all material for which you do not
 | 
			
		||||
control copyright. Those thus making or running the covered works for
 | 
			
		||||
you must do so exclusively on your behalf, under your direction and
 | 
			
		||||
control, on terms that prohibit them from making any copies of your
 | 
			
		||||
copyrighted material outside their relationship with you.
 | 
			
		||||
 | 
			
		||||
Conveying under any other circumstances is permitted solely under the
 | 
			
		||||
conditions stated below. Sublicensing is not allowed; section 10 makes
 | 
			
		||||
it unnecessary.
 | 
			
		||||
 | 
			
		||||
#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 | 
			
		||||
 | 
			
		||||
No covered work shall be deemed part of an effective technological
 | 
			
		||||
measure under any applicable law fulfilling obligations under article
 | 
			
		||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
 | 
			
		||||
similar laws prohibiting or restricting circumvention of such
 | 
			
		||||
measures.
 | 
			
		||||
 | 
			
		||||
When you convey a covered work, you waive any legal power to forbid
 | 
			
		||||
circumvention of technological measures to the extent such
 | 
			
		||||
circumvention is effected by exercising rights under this License with
 | 
			
		||||
respect to the covered work, and you disclaim any intention to limit
 | 
			
		||||
operation or modification of the work as a means of enforcing, against
 | 
			
		||||
the work's users, your or third parties' legal rights to forbid
 | 
			
		||||
circumvention of technological measures.
 | 
			
		||||
 | 
			
		||||
#### 4. Conveying Verbatim Copies.
 | 
			
		||||
 | 
			
		||||
You may convey verbatim copies of the Program's source code as you
 | 
			
		||||
receive it, in any medium, provided that you conspicuously and
 | 
			
		||||
appropriately publish on each copy an appropriate copyright notice;
 | 
			
		||||
keep intact all notices stating that this License and any
 | 
			
		||||
non-permissive terms added in accord with section 7 apply to the code;
 | 
			
		||||
keep intact all notices of the absence of any warranty; and give all
 | 
			
		||||
recipients a copy of this License along with the Program.
 | 
			
		||||
 | 
			
		||||
You may charge any price or no price for each copy that you convey,
 | 
			
		||||
and you may offer support or warranty protection for a fee.
 | 
			
		||||
 | 
			
		||||
#### 5. Conveying Modified Source Versions.
 | 
			
		||||
 | 
			
		||||
You may convey a work based on the Program, or the modifications to
 | 
			
		||||
produce it from the Program, in the form of source code under the
 | 
			
		||||
terms of section 4, provided that you also meet all of these
 | 
			
		||||
conditions:
 | 
			
		||||
 | 
			
		||||
-   a) The work must carry prominent notices stating that you modified
 | 
			
		||||
    it, and giving a relevant date.
 | 
			
		||||
-   b) The work must carry prominent notices stating that it is
 | 
			
		||||
    released under this License and any conditions added under
 | 
			
		||||
    section 7. This requirement modifies the requirement in section 4
 | 
			
		||||
    to "keep intact all notices".
 | 
			
		||||
-   c) You must license the entire work, as a whole, under this
 | 
			
		||||
    License to anyone who comes into possession of a copy. This
 | 
			
		||||
    License will therefore apply, along with any applicable section 7
 | 
			
		||||
    additional terms, to the whole of the work, and all its parts,
 | 
			
		||||
    regardless of how they are packaged. This License gives no
 | 
			
		||||
    permission to license the work in any other way, but it does not
 | 
			
		||||
    invalidate such permission if you have separately received it.
 | 
			
		||||
-   d) If the work has interactive user interfaces, each must display
 | 
			
		||||
    Appropriate Legal Notices; however, if the Program has interactive
 | 
			
		||||
    interfaces that do not display Appropriate Legal Notices, your
 | 
			
		||||
    work need not make them do so.
 | 
			
		||||
 | 
			
		||||
A compilation of a covered work with other separate and independent
 | 
			
		||||
works, which are not by their nature extensions of the covered work,
 | 
			
		||||
and which are not combined with it such as to form a larger program,
 | 
			
		||||
in or on a volume of a storage or distribution medium, is called an
 | 
			
		||||
"aggregate" if the compilation and its resulting copyright are not
 | 
			
		||||
used to limit the access or legal rights of the compilation's users
 | 
			
		||||
beyond what the individual works permit. Inclusion of a covered work
 | 
			
		||||
in an aggregate does not cause this License to apply to the other
 | 
			
		||||
parts of the aggregate.
 | 
			
		||||
 | 
			
		||||
#### 6. Conveying Non-Source Forms.
 | 
			
		||||
 | 
			
		||||
You may convey a covered work in object code form under the terms of
 | 
			
		||||
sections 4 and 5, provided that you also convey the machine-readable
 | 
			
		||||
Corresponding Source under the terms of this License, in one of these
 | 
			
		||||
ways:
 | 
			
		||||
 | 
			
		||||
-   a) Convey the object code in, or embodied in, a physical product
 | 
			
		||||
    (including a physical distribution medium), accompanied by the
 | 
			
		||||
    Corresponding Source fixed on a durable physical medium
 | 
			
		||||
    customarily used for software interchange.
 | 
			
		||||
-   b) Convey the object code in, or embodied in, a physical product
 | 
			
		||||
    (including a physical distribution medium), accompanied by a
 | 
			
		||||
    written offer, valid for at least three years and valid for as
 | 
			
		||||
    long as you offer spare parts or customer support for that product
 | 
			
		||||
    model, to give anyone who possesses the object code either (1) a
 | 
			
		||||
    copy of the Corresponding Source for all the software in the
 | 
			
		||||
    product that is covered by this License, on a durable physical
 | 
			
		||||
    medium customarily used for software interchange, for a price no
 | 
			
		||||
    more than your reasonable cost of physically performing this
 | 
			
		||||
    conveying of source, or (2) access to copy the Corresponding
 | 
			
		||||
    Source from a network server at no charge.
 | 
			
		||||
-   c) Convey individual copies of the object code with a copy of the
 | 
			
		||||
    written offer to provide the Corresponding Source. This
 | 
			
		||||
    alternative is allowed only occasionally and noncommercially, and
 | 
			
		||||
    only if you received the object code with such an offer, in accord
 | 
			
		||||
    with subsection 6b.
 | 
			
		||||
-   d) Convey the object code by offering access from a designated
 | 
			
		||||
    place (gratis or for a charge), and offer equivalent access to the
 | 
			
		||||
    Corresponding Source in the same way through the same place at no
 | 
			
		||||
    further charge. You need not require recipients to copy the
 | 
			
		||||
    Corresponding Source along with the object code. If the place to
 | 
			
		||||
    copy the object code is a network server, the Corresponding Source
 | 
			
		||||
    may be on a different server (operated by you or a third party)
 | 
			
		||||
    that supports equivalent copying facilities, provided you maintain
 | 
			
		||||
    clear directions next to the object code saying where to find the
 | 
			
		||||
    Corresponding Source. Regardless of what server hosts the
 | 
			
		||||
    Corresponding Source, you remain obligated to ensure that it is
 | 
			
		||||
    available for as long as needed to satisfy these requirements.
 | 
			
		||||
-   e) Convey the object code using peer-to-peer transmission,
 | 
			
		||||
    provided you inform other peers where the object code and
 | 
			
		||||
    Corresponding Source of the work are being offered to the general
 | 
			
		||||
    public at no charge under subsection 6d.
 | 
			
		||||
 | 
			
		||||
A separable portion of the object code, whose source code is excluded
 | 
			
		||||
from the Corresponding Source as a System Library, need not be
 | 
			
		||||
included in conveying the object code work.
 | 
			
		||||
 | 
			
		||||
A "User Product" is either (1) a "consumer product", which means any
 | 
			
		||||
tangible personal property which is normally used for personal,
 | 
			
		||||
family, or household purposes, or (2) anything designed or sold for
 | 
			
		||||
incorporation into a dwelling. In determining whether a product is a
 | 
			
		||||
consumer product, doubtful cases shall be resolved in favor of
 | 
			
		||||
coverage. For a particular product received by a particular user,
 | 
			
		||||
"normally used" refers to a typical or common use of that class of
 | 
			
		||||
product, regardless of the status of the particular user or of the way
 | 
			
		||||
in which the particular user actually uses, or expects or is expected
 | 
			
		||||
to use, the product. A product is a consumer product regardless of
 | 
			
		||||
whether the product has substantial commercial, industrial or
 | 
			
		||||
non-consumer uses, unless such uses represent the only significant
 | 
			
		||||
mode of use of the product.
 | 
			
		||||
 | 
			
		||||
"Installation Information" for a User Product means any methods,
 | 
			
		||||
procedures, authorization keys, or other information required to
 | 
			
		||||
install and execute modified versions of a covered work in that User
 | 
			
		||||
Product from a modified version of its Corresponding Source. The
 | 
			
		||||
information must suffice to ensure that the continued functioning of
 | 
			
		||||
the modified object code is in no case prevented or interfered with
 | 
			
		||||
solely because modification has been made.
 | 
			
		||||
 | 
			
		||||
If you convey an object code work under this section in, or with, or
 | 
			
		||||
specifically for use in, a User Product, and the conveying occurs as
 | 
			
		||||
part of a transaction in which the right of possession and use of the
 | 
			
		||||
User Product is transferred to the recipient in perpetuity or for a
 | 
			
		||||
fixed term (regardless of how the transaction is characterized), the
 | 
			
		||||
Corresponding Source conveyed under this section must be accompanied
 | 
			
		||||
by the Installation Information. But this requirement does not apply
 | 
			
		||||
if neither you nor any third party retains the ability to install
 | 
			
		||||
modified object code on the User Product (for example, the work has
 | 
			
		||||
been installed in ROM).
 | 
			
		||||
 | 
			
		||||
The requirement to provide Installation Information does not include a
 | 
			
		||||
requirement to continue to provide support service, warranty, or
 | 
			
		||||
updates for a work that has been modified or installed by the
 | 
			
		||||
recipient, or for the User Product in which it has been modified or
 | 
			
		||||
installed. Access to a network may be denied when the modification
 | 
			
		||||
itself materially and adversely affects the operation of the network
 | 
			
		||||
or violates the rules and protocols for communication across the
 | 
			
		||||
network.
 | 
			
		||||
 | 
			
		||||
Corresponding Source conveyed, and Installation Information provided,
 | 
			
		||||
in accord with this section must be in a format that is publicly
 | 
			
		||||
documented (and with an implementation available to the public in
 | 
			
		||||
source code form), and must require no special password or key for
 | 
			
		||||
unpacking, reading or copying.
 | 
			
		||||
 | 
			
		||||
#### 7. Additional Terms.
 | 
			
		||||
 | 
			
		||||
"Additional permissions" are terms that supplement the terms of this
 | 
			
		||||
License by making exceptions from one or more of its conditions.
 | 
			
		||||
Additional permissions that are applicable to the entire Program shall
 | 
			
		||||
be treated as though they were included in this License, to the extent
 | 
			
		||||
that they are valid under applicable law. If additional permissions
 | 
			
		||||
apply only to part of the Program, that part may be used separately
 | 
			
		||||
under those permissions, but the entire Program remains governed by
 | 
			
		||||
this License without regard to the additional permissions.
 | 
			
		||||
 | 
			
		||||
When you convey a copy of a covered work, you may at your option
 | 
			
		||||
remove any additional permissions from that copy, or from any part of
 | 
			
		||||
it. (Additional permissions may be written to require their own
 | 
			
		||||
removal in certain cases when you modify the work.) You may place
 | 
			
		||||
additional permissions on material, added by you to a covered work,
 | 
			
		||||
for which you have or can give appropriate copyright permission.
 | 
			
		||||
 | 
			
		||||
Notwithstanding any other provision of this License, for material you
 | 
			
		||||
add to a covered work, you may (if authorized by the copyright holders
 | 
			
		||||
of that material) supplement the terms of this License with terms:
 | 
			
		||||
 | 
			
		||||
-   a) Disclaiming warranty or limiting liability differently from the
 | 
			
		||||
    terms of sections 15 and 16 of this License; or
 | 
			
		||||
-   b) Requiring preservation of specified reasonable legal notices or
 | 
			
		||||
    author attributions in that material or in the Appropriate Legal
 | 
			
		||||
    Notices displayed by works containing it; or
 | 
			
		||||
-   c) Prohibiting misrepresentation of the origin of that material,
 | 
			
		||||
    or requiring that modified versions of such material be marked in
 | 
			
		||||
    reasonable ways as different from the original version; or
 | 
			
		||||
-   d) Limiting the use for publicity purposes of names of licensors
 | 
			
		||||
    or authors of the material; or
 | 
			
		||||
-   e) Declining to grant rights under trademark law for use of some
 | 
			
		||||
    trade names, trademarks, or service marks; or
 | 
			
		||||
-   f) Requiring indemnification of licensors and authors of that
 | 
			
		||||
    material by anyone who conveys the material (or modified versions
 | 
			
		||||
    of it) with contractual assumptions of liability to the recipient,
 | 
			
		||||
    for any liability that these contractual assumptions directly
 | 
			
		||||
    impose on those licensors and authors.
 | 
			
		||||
 | 
			
		||||
All other non-permissive additional terms are considered "further
 | 
			
		||||
restrictions" within the meaning of section 10. If the Program as you
 | 
			
		||||
received it, or any part of it, contains a notice stating that it is
 | 
			
		||||
governed by this License along with a term that is a further
 | 
			
		||||
restriction, you may remove that term. If a license document contains
 | 
			
		||||
a further restriction but permits relicensing or conveying under this
 | 
			
		||||
License, you may add to a covered work material governed by the terms
 | 
			
		||||
of that license document, provided that the further restriction does
 | 
			
		||||
not survive such relicensing or conveying.
 | 
			
		||||
 | 
			
		||||
If you add terms to a covered work in accord with this section, you
 | 
			
		||||
must place, in the relevant source files, a statement of the
 | 
			
		||||
additional terms that apply to those files, or a notice indicating
 | 
			
		||||
where to find the applicable terms.
 | 
			
		||||
 | 
			
		||||
Additional terms, permissive or non-permissive, may be stated in the
 | 
			
		||||
form of a separately written license, or stated as exceptions; the
 | 
			
		||||
above requirements apply either way.
 | 
			
		||||
 | 
			
		||||
#### 8. Termination.
 | 
			
		||||
 | 
			
		||||
You may not propagate or modify a covered work except as expressly
 | 
			
		||||
provided under this License. Any attempt otherwise to propagate or
 | 
			
		||||
modify it is void, and will automatically terminate your rights under
 | 
			
		||||
this License (including any patent licenses granted under the third
 | 
			
		||||
paragraph of section 11).
 | 
			
		||||
 | 
			
		||||
However, if you cease all violation of this License, then your license
 | 
			
		||||
from a particular copyright holder is reinstated (a) provisionally,
 | 
			
		||||
unless and until the copyright holder explicitly and finally
 | 
			
		||||
terminates your license, and (b) permanently, if the copyright holder
 | 
			
		||||
fails to notify you of the violation by some reasonable means prior to
 | 
			
		||||
60 days after the cessation.
 | 
			
		||||
 | 
			
		||||
Moreover, your license from a particular copyright holder is
 | 
			
		||||
reinstated permanently if the copyright holder notifies you of the
 | 
			
		||||
violation by some reasonable means, this is the first time you have
 | 
			
		||||
received notice of violation of this License (for any work) from that
 | 
			
		||||
copyright holder, and you cure the violation prior to 30 days after
 | 
			
		||||
your receipt of the notice.
 | 
			
		||||
 | 
			
		||||
Termination of your rights under this section does not terminate the
 | 
			
		||||
licenses of parties who have received copies or rights from you under
 | 
			
		||||
this License. If your rights have been terminated and not permanently
 | 
			
		||||
reinstated, you do not qualify to receive new licenses for the same
 | 
			
		||||
material under section 10.
 | 
			
		||||
 | 
			
		||||
#### 9. Acceptance Not Required for Having Copies.
 | 
			
		||||
 | 
			
		||||
You are not required to accept this License in order to receive or run
 | 
			
		||||
a copy of the Program. Ancillary propagation of a covered work
 | 
			
		||||
occurring solely as a consequence of using peer-to-peer transmission
 | 
			
		||||
to receive a copy likewise does not require acceptance. However,
 | 
			
		||||
nothing other than this License grants you permission to propagate or
 | 
			
		||||
modify any covered work. These actions infringe copyright if you do
 | 
			
		||||
not accept this License. Therefore, by modifying or propagating a
 | 
			
		||||
covered work, you indicate your acceptance of this License to do so.
 | 
			
		||||
 | 
			
		||||
#### 10. Automatic Licensing of Downstream Recipients.
 | 
			
		||||
 | 
			
		||||
Each time you convey a covered work, the recipient automatically
 | 
			
		||||
receives a license from the original licensors, to run, modify and
 | 
			
		||||
propagate that work, subject to this License. You are not responsible
 | 
			
		||||
for enforcing compliance by third parties with this License.
 | 
			
		||||
 | 
			
		||||
An "entity transaction" is a transaction transferring control of an
 | 
			
		||||
organization, or substantially all assets of one, or subdividing an
 | 
			
		||||
organization, or merging organizations. If propagation of a covered
 | 
			
		||||
work results from an entity transaction, each party to that
 | 
			
		||||
transaction who receives a copy of the work also receives whatever
 | 
			
		||||
licenses to the work the party's predecessor in interest had or could
 | 
			
		||||
give under the previous paragraph, plus a right to possession of the
 | 
			
		||||
Corresponding Source of the work from the predecessor in interest, if
 | 
			
		||||
the predecessor has it or can get it with reasonable efforts.
 | 
			
		||||
 | 
			
		||||
You may not impose any further restrictions on the exercise of the
 | 
			
		||||
rights granted or affirmed under this License. For example, you may
 | 
			
		||||
not impose a license fee, royalty, or other charge for exercise of
 | 
			
		||||
rights granted under this License, and you may not initiate litigation
 | 
			
		||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
 | 
			
		||||
any patent claim is infringed by making, using, selling, offering for
 | 
			
		||||
sale, or importing the Program or any portion of it.
 | 
			
		||||
 | 
			
		||||
#### 11. Patents.
 | 
			
		||||
 | 
			
		||||
A "contributor" is a copyright holder who authorizes use under this
 | 
			
		||||
License of the Program or a work on which the Program is based. The
 | 
			
		||||
work thus licensed is called the contributor's "contributor version".
 | 
			
		||||
 | 
			
		||||
A contributor's "essential patent claims" are all patent claims owned
 | 
			
		||||
or controlled by the contributor, whether already acquired or
 | 
			
		||||
hereafter acquired, that would be infringed by some manner, permitted
 | 
			
		||||
by this License, of making, using, or selling its contributor version,
 | 
			
		||||
but do not include claims that would be infringed only as a
 | 
			
		||||
consequence of further modification of the contributor version. For
 | 
			
		||||
purposes of this definition, "control" includes the right to grant
 | 
			
		||||
patent sublicenses in a manner consistent with the requirements of
 | 
			
		||||
this License.
 | 
			
		||||
 | 
			
		||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
 | 
			
		||||
patent license under the contributor's essential patent claims, to
 | 
			
		||||
make, use, sell, offer for sale, import and otherwise run, modify and
 | 
			
		||||
propagate the contents of its contributor version.
 | 
			
		||||
 | 
			
		||||
In the following three paragraphs, a "patent license" is any express
 | 
			
		||||
agreement or commitment, however denominated, not to enforce a patent
 | 
			
		||||
(such as an express permission to practice a patent or covenant not to
 | 
			
		||||
sue for patent infringement). To "grant" such a patent license to a
 | 
			
		||||
party means to make such an agreement or commitment not to enforce a
 | 
			
		||||
patent against the party.
 | 
			
		||||
 | 
			
		||||
If you convey a covered work, knowingly relying on a patent license,
 | 
			
		||||
and the Corresponding Source of the work is not available for anyone
 | 
			
		||||
to copy, free of charge and under the terms of this License, through a
 | 
			
		||||
publicly available network server or other readily accessible means,
 | 
			
		||||
then you must either (1) cause the Corresponding Source to be so
 | 
			
		||||
available, or (2) arrange to deprive yourself of the benefit of the
 | 
			
		||||
patent license for this particular work, or (3) arrange, in a manner
 | 
			
		||||
consistent with the requirements of this License, to extend the patent
 | 
			
		||||
license to downstream recipients. "Knowingly relying" means you have
 | 
			
		||||
actual knowledge that, but for the patent license, your conveying the
 | 
			
		||||
covered work in a country, or your recipient's use of the covered work
 | 
			
		||||
in a country, would infringe one or more identifiable patents in that
 | 
			
		||||
country that you have reason to believe are valid.
 | 
			
		||||
 | 
			
		||||
If, pursuant to or in connection with a single transaction or
 | 
			
		||||
arrangement, you convey, or propagate by procuring conveyance of, a
 | 
			
		||||
covered work, and grant a patent license to some of the parties
 | 
			
		||||
receiving the covered work authorizing them to use, propagate, modify
 | 
			
		||||
or convey a specific copy of the covered work, then the patent license
 | 
			
		||||
you grant is automatically extended to all recipients of the covered
 | 
			
		||||
work and works based on it.
 | 
			
		||||
 | 
			
		||||
A patent license is "discriminatory" if it does not include within the
 | 
			
		||||
scope of its coverage, prohibits the exercise of, or is conditioned on
 | 
			
		||||
the non-exercise of one or more of the rights that are specifically
 | 
			
		||||
granted under this License. You may not convey a covered work if you
 | 
			
		||||
are a party to an arrangement with a third party that is in the
 | 
			
		||||
business of distributing software, under which you make payment to the
 | 
			
		||||
third party based on the extent of your activity of conveying the
 | 
			
		||||
work, and under which the third party grants, to any of the parties
 | 
			
		||||
who would receive the covered work from you, a discriminatory patent
 | 
			
		||||
license (a) in connection with copies of the covered work conveyed by
 | 
			
		||||
you (or copies made from those copies), or (b) primarily for and in
 | 
			
		||||
connection with specific products or compilations that contain the
 | 
			
		||||
covered work, unless you entered into that arrangement, or that patent
 | 
			
		||||
license was granted, prior to 28 March 2007.
 | 
			
		||||
 | 
			
		||||
Nothing in this License shall be construed as excluding or limiting
 | 
			
		||||
any implied license or other defenses to infringement that may
 | 
			
		||||
otherwise be available to you under applicable patent law.
 | 
			
		||||
 | 
			
		||||
#### 12. No Surrender of Others' Freedom.
 | 
			
		||||
 | 
			
		||||
If conditions are imposed on you (whether by court order, agreement or
 | 
			
		||||
otherwise) that contradict the conditions of this License, they do not
 | 
			
		||||
excuse you from the conditions of this License. If you cannot convey a
 | 
			
		||||
covered work so as to satisfy simultaneously your obligations under
 | 
			
		||||
this License and any other pertinent obligations, then as a
 | 
			
		||||
consequence you may not convey it at all. For example, if you agree to
 | 
			
		||||
terms that obligate you to collect a royalty for further conveying
 | 
			
		||||
from those to whom you convey the Program, the only way you could
 | 
			
		||||
satisfy both those terms and this License would be to refrain entirely
 | 
			
		||||
from conveying the Program.
 | 
			
		||||
 | 
			
		||||
#### 13. Remote Network Interaction; Use with the GNU General Public License.
 | 
			
		||||
 | 
			
		||||
Notwithstanding any other provision of this License, if you modify the
 | 
			
		||||
Program, your modified version must prominently offer all users
 | 
			
		||||
interacting with it remotely through a computer network (if your
 | 
			
		||||
version supports such interaction) an opportunity to receive the
 | 
			
		||||
Corresponding Source of your version by providing access to the
 | 
			
		||||
Corresponding Source from a network server at no charge, through some
 | 
			
		||||
standard or customary means of facilitating copying of software. This
 | 
			
		||||
Corresponding Source shall include the Corresponding Source for any
 | 
			
		||||
work covered by version 3 of the GNU General Public License that is
 | 
			
		||||
incorporated pursuant to the following paragraph.
 | 
			
		||||
 | 
			
		||||
Notwithstanding any other provision of this License, you have
 | 
			
		||||
permission to link or combine any covered work with a work licensed
 | 
			
		||||
under version 3 of the GNU General Public License into a single
 | 
			
		||||
combined work, and to convey the resulting work. The terms of this
 | 
			
		||||
License will continue to apply to the part which is the covered work,
 | 
			
		||||
but the work with which it is combined will remain governed by version
 | 
			
		||||
3 of the GNU General Public License.
 | 
			
		||||
 | 
			
		||||
#### 14. Revised Versions of this License.
 | 
			
		||||
 | 
			
		||||
The Free Software Foundation may publish revised and/or new versions
 | 
			
		||||
of the GNU Affero General Public License from time to time. Such new
 | 
			
		||||
versions will be similar in spirit to the present version, but may
 | 
			
		||||
differ in detail to address new problems or concerns.
 | 
			
		||||
 | 
			
		||||
Each version is given a distinguishing version number. If the Program
 | 
			
		||||
specifies that a certain numbered version of the GNU Affero General
 | 
			
		||||
Public License "or any later version" applies to it, you have the
 | 
			
		||||
option of following the terms and conditions either of that numbered
 | 
			
		||||
version or of any later version published by the Free Software
 | 
			
		||||
Foundation. If the Program does not specify a version number of the
 | 
			
		||||
GNU Affero General Public License, you may choose any version ever
 | 
			
		||||
published by the Free Software Foundation.
 | 
			
		||||
 | 
			
		||||
If the Program specifies that a proxy can decide which future versions
 | 
			
		||||
of the GNU Affero General Public License can be used, that proxy's
 | 
			
		||||
public statement of acceptance of a version permanently authorizes you
 | 
			
		||||
to choose that version for the Program.
 | 
			
		||||
 | 
			
		||||
Later license versions may give you additional or different
 | 
			
		||||
permissions. However, no additional obligations are imposed on any
 | 
			
		||||
author or copyright holder as a result of your choosing to follow a
 | 
			
		||||
later version.
 | 
			
		||||
 | 
			
		||||
#### 15. Disclaimer of Warranty.
 | 
			
		||||
 | 
			
		||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 | 
			
		||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 | 
			
		||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
 | 
			
		||||
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
 | 
			
		||||
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
 | 
			
		||||
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
 | 
			
		||||
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
 | 
			
		||||
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
 | 
			
		||||
CORRECTION.
 | 
			
		||||
 | 
			
		||||
#### 16. Limitation of Liability.
 | 
			
		||||
 | 
			
		||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 | 
			
		||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
 | 
			
		||||
CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 | 
			
		||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
 | 
			
		||||
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
 | 
			
		||||
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
 | 
			
		||||
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
 | 
			
		||||
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
 | 
			
		||||
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 | 
			
		||||
 | 
			
		||||
#### 17. Interpretation of Sections 15 and 16.
 | 
			
		||||
 | 
			
		||||
If the disclaimer of warranty and limitation of liability provided
 | 
			
		||||
above cannot be given local legal effect according to their terms,
 | 
			
		||||
reviewing courts shall apply local law that most closely approximates
 | 
			
		||||
an absolute waiver of all civil liability in connection with the
 | 
			
		||||
Program, unless a warranty or assumption of liability accompanies a
 | 
			
		||||
copy of the Program in return for a fee.
 | 
			
		||||
 | 
			
		||||
END OF TERMS AND CONDITIONS
 | 
			
		||||
 | 
			
		||||
### How to Apply These Terms to Your New Programs
 | 
			
		||||
 | 
			
		||||
If you develop a new program, and you want it to be of the greatest
 | 
			
		||||
possible use to the public, the best way to achieve this is to make it
 | 
			
		||||
free software which everyone can redistribute and change under these
 | 
			
		||||
terms.
 | 
			
		||||
 | 
			
		||||
To do so, attach the following notices to the program. It is safest to
 | 
			
		||||
attach them to the start of each source file to most effectively state
 | 
			
		||||
the exclusion of warranty; and each file should have at least the
 | 
			
		||||
"copyright" line and a pointer to where the full notice is found.
 | 
			
		||||
 | 
			
		||||
        <one line to give the program's name and a brief idea of what it does.>
 | 
			
		||||
        Copyright (C) <year>  <name of author>
 | 
			
		||||
 | 
			
		||||
        This program is free software: you can redistribute it and/or modify
 | 
			
		||||
        it under the terms of the GNU Affero General Public License as
 | 
			
		||||
        published by the Free Software Foundation, either version 3 of the
 | 
			
		||||
        License, or (at your option) any later version.
 | 
			
		||||
 | 
			
		||||
        This program is distributed in the hope that it will be useful,
 | 
			
		||||
        but WITHOUT ANY WARRANTY; without even the implied warranty of
 | 
			
		||||
        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 | 
			
		||||
        GNU Affero General Public License for more details.
 | 
			
		||||
 | 
			
		||||
        You should have received a copy of the GNU Affero General Public License
 | 
			
		||||
        along with this program.  If not, see <https://www.gnu.org/licenses/>.
 | 
			
		||||
 | 
			
		||||
Also add information on how to contact you by electronic and paper
 | 
			
		||||
mail.
 | 
			
		||||
 | 
			
		||||
If your software can interact with users remotely through a computer
 | 
			
		||||
network, you should also make sure that it provides a way for users to
 | 
			
		||||
get its source. For example, if your program is a web application, its
 | 
			
		||||
interface could display a "Source" link that leads users to an archive
 | 
			
		||||
of the code. There are many ways you could offer source, and different
 | 
			
		||||
solutions will be better for different programs; see section 13 for
 | 
			
		||||
the specific requirements.
 | 
			
		||||
 | 
			
		||||
You should also get your employer (if you work as a programmer) or
 | 
			
		||||
school, if any, to sign a "copyright disclaimer" for the program, if
 | 
			
		||||
necessary. For more information on this, and how to apply and follow
 | 
			
		||||
the GNU AGPL, see <https://www.gnu.org/licenses/>.

# Laskutin
 | 
			
		||||
 | 
			
		||||
Laskutin on yksinkertainen massalaskutusohjelma, jolla voidaan sähköpostittaa
 | 
			
		||||
ja hallinnoida CSV-tiedostoon kirjattuja laskuja. Laskutin osaa lähettää CSV:n
 | 
			
		||||
perusteella laskut ja maksumuistutukset, päivittää maksutilanteen
 | 
			
		||||
verkkopankista ladatusta tilitapahtumalistasta ja tulostaa tiivistelmän
 | 
			
		||||
maksujen tilanteesta.
 | 
			
		||||
 | 
			
		||||
Esimerkiksi databileiden osallistumismaksujen ja datatuotetilausten
 | 
			
		||||
laskuttamisessa on käytetty Laskutinta.
 | 
			
		||||
 | 
			
		||||
## Asentaminen
 | 
			
		||||
 | 
			
		||||
Lisää tämä git-tietovaranto [Guixin kanavalistaan][guix-channels]
 | 
			
		||||
seuraavankaltaisella pätkällä:
 | 
			
		||||
 | 
			
		||||
[guix-channels]: https://guix.gnu.org/manual/devel/en/guix.html#Specifying-Additional-Channels
 | 
			
		||||
 | 
			
		||||
```lisp
 | 
			
		||||
(channel
 | 
			
		||||
 (name 'laskutin)
 | 
			
		||||
 (url "https://git.datat.fi/ry/laskutin")
 | 
			
		||||
 (branch "main")
 | 
			
		||||
 (introduction
 | 
			
		||||
  (make-channel-introduction
 | 
			
		||||
   "3c3f4f7992ed98ebc7fc0d96169d6d2283cb5386"
 | 
			
		||||
   (openpgp-fingerprint
 | 
			
		||||
    "A0C9 1947 734F 076F 5F08 E9FF 257D 284A 2A1D 3A32"))))
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Tämän jälkeen Laskutin on saatavilla `laskutin`-nimisenä pakettina kaikkialla
 | 
			
		||||
Guixissa. Voit esimerkiksi ottaa sen käyttöön komentotulkkisessioosi komennolla
 | 
			
		||||
`guix shell laskutin`.
 | 
			
		||||
 | 
			
		||||
## Ajaminen
 | 
			
		||||
 | 
			
		||||
Yleensä laskuttimen käyttö etenee seuraavasti:
 | 
			
		||||
 | 
			
		||||
1. Määritä laskut CSV-tiedostoon [mallin](./esimerkki.csv) mukaisesti
 | 
			
		||||
2. Aja `laskutin send`
 | 
			
		||||
3. Hae verkkopankista CSV-tiedosto tilitapahtumista
 | 
			
		||||
4. Aja `laskutin update`
 | 
			
		||||
5. Aja `laskutin status`
 | 
			
		||||
6. Jos kaikkia laskuja ei ole vielä maksettu, aja `laskutin send --reminders`
 | 
			
		||||
   ja palaa kohtaan 3.
 | 
			
		||||
 | 
			
		||||
Jokaiselle komennolle tarvitsee määrittää oikeat asetukset komentorivillä
 | 
			
		||||
annettavilla valitsimilla. Mahdolliset valitsimet voi listata kirjoittamalla
 | 
			
		||||
komennon perään `--help`-valitsimen.
 | 
			
		||||
 | 
			
		||||
## Kehittäminen
 | 
			
		||||
 | 
			
		||||
Kehitysympäristön saat helposti Guixilla ajamalla komennon [`guix
 | 
			
		||||
shell`][guix-shell] tässä hakemistossa. Muutoksia, vikailmoituksia ja
 | 
			
		||||
kehitysideoita voi jättää Giteassa tai sähköpostilla osoitteeseen
 | 
			
		||||
<saku@laesvuori.fi>. Tarkista, että laskutin kääntyy vielä muutostesi jälkeen
 | 
			
		||||
ajamalla komento `guix time-machine -C channels.scm -- build -f guix.scm`.
 | 
			
		||||
 | 
			
		||||
[guix-shell]: https://guix.gnu.org/manual/devel/en/guix.html#Invoking-guix-shell
 | 
			
		||||
 | 
			
		||||
## Kopioiminen
 | 
			
		||||
 | 
			
		||||
Laskutin on [GNU AGPL lisenssin version kolme](COPYING.md), tai valintasi
 | 
			
		||||
mukaan minkä tahansa myöhemmän [Free Software Foundationin julkaiseman
 | 
			
		||||
version][fsf-agpl], alainen vapaa ohjelma, eli se kunniottaa käyttäjiensä
 | 
			
		||||
vapautta päättää itse omasta tietojenkäsittelystään ja auttaa toisiaan.
