<h1><a class="toc-backref" href="#id5" id="abstract" name="abstract">Abstract</a></h1>
<p>Currently, every ebuild in the main gentoo repository is required to have a
valid LICENSE entry.  However, the syntax of this entry is not officially
defined and the entry itself is only used when outputting package
details.</p>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id6" id="status-update" name="status-update">Status Update</a></h1>
<p>Repoman has been updated to check for the LICENSE syntax.
A development portage branch with support for ACCEPT_LICENSE
and license groups exists.</p>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id7" id="motivation" name="motivation">Motivation</a></h1>
<p>Many users wish to regulate the software they install with regards to
licenses for various reasons <a class="footnote-reference" href="#id3" id="id1" name="id1">[1]</a>.  Some want a system free of any
software that is not OSI-approved; others are simply curious as to what
licenses they are implicitly accepting.</p>
<p>Furthermore, some software requires that a user interactively accept its
license for its author's to consider it legally binding.  This is
currently implemented using <tt class="docutils literal"><span class="pre">eutils.eclass</span></tt>.</p>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id8" id="specification" name="specification">Specification</a></h1>
<div class="section">
<h2><a class="toc-backref" href="#id9" id="ebuild-license-variable" name="ebuild-license-variable">Ebuild LICENSE Variable</a></h2>
<p>Most ebuilds are for software which is released under a single license.
In these cases, the current LICENSE variable can remain as is.  For
example:</p>
<pre class="literal-block">
LICENSE=&quot;single-license&quot;
</pre>
<p>However, there are several ebuilds for software which is released under
several licenses, of which the user must accept one, some or all <a class="footnote-reference" href="#id4" id="id2" name="id2">[2]</a>.
To complicate this, some ebuilds include optional components which fall
under a different license.</p>
<p>To accomodate these cases, LICENSE syntax should accomodate all
functionality offered by a DEPEND string.  To keep things simple, this
GLEP proposes that the syntax be identical.  For example:</p>
<pre class="literal-block">
LICENSE=&quot;mandatory-license
    || ( choosable-licence1 chooseable-license-2 )
    useflag? ( optional-component-license )&quot;
</pre>
<p>License names may contain [a-zA-Z0-9] (english alphanumeric characters),
_ (underscore), - (dash), . (dot) and + (plus sign).</p>
</div>
<div class="section">
<h2><a class="toc-backref" href="#id10" id="license-groups" name="license-groups">License Groups</a></h2>
<p>Almost all users are willing to install any software that is
FSF-approved.  Other users are willing to install any software and
implicitly accept its license.  To this end, implementations will also
need to handle grouping of licenses.</p>
<p>At a minimum, there needs to be the groups <tt class="docutils literal"><span class="pre">GPL-COMPATIBLE</span></tt>,
<tt class="docutils literal"><span class="pre">FSF-APPROVED</span></tt>, <tt class="docutils literal"><span class="pre">OSI-APPROVED</span></tt> and <tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt>.
<tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt> licenses are those that don't require manual
acceptance for to be considered legally binding.  This is the current
behaviour of portage.</p>
<p>These groups are defined in a new file <tt class="docutils literal"><span class="pre">license_groups</span></tt> in
the <tt class="docutils literal"><span class="pre">profiles</span></tt> subdirectory of the tree (or overlays).
Details of handling groups defined in overlays is implementation dependent.</p>
<p>The format of this file is</p>
<pre class="literal-block">
&lt;groupname&gt; &lt;license1&gt; &lt;license2&gt; ... &lt;licenseN&gt;
</pre>
<p>Also any line starting with # is ignored and may be used for comments.
Group names use the same syntax as normal license names. Also license groups
may contain other groups.
License groups may not contain negated elements, so a group</p>
<pre class="literal-block">
mygroup foo -bar -bla
</pre>
<p>is illegal.</p>
</div>
<div class="section">
<h2><a class="toc-backref" href="#id11" id="accept-license" name="accept-license">ACCEPT_LICENSE</a></h2>
<p>This GLEP proposes that a user be able to explicitly accept or decline
licenses by editing a new variable <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> in
<tt class="docutils literal"><span class="pre">/etc/make.conf</span></tt>.  Again, to keep things simple, the syntax should be
similar to that of other incrementals.  For example:</p>
<pre class="literal-block">
ACCEPT_LICENSE=&quot;-* accepted-license -declined-license&quot;
</pre>
<p>As an extension, <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> must also support <a class="reference" href="#license-groups">license groups</a>.
This GLEP proposes that the license group be prepended by the special
character &quot;<tt class="docutils literal"><span class="pre">&#64;</span></tt>&quot;.  For example:</p>
<pre class="literal-block">
ACCEPT_LICENSE=&quot;-* &#64;FSF-APPROVED&quot;
</pre>
<p>License groups may be negated with the result that all elements of that group
are also negated.</p>
<p>Portage will also offer a package.license facility to offer this functionality
on a per-package base (analog to package.keywords), other implementations may
implement such a facility differently or not at all.</p>
</div>
<div class="section">
<h2><a class="toc-backref" href="#id12" id="behaviour" name="behaviour">Behaviour</a></h2>
<p>Unaccepted licenses will be treated like any other masked package, that is
the user interface of an implementation will display a message listing any
license that has to be accepted before the package can be merged with a
pointer to the exact license text.</p>
<p>Past versions of this document proposed to handle license-masked packages
like blockers, but this would be inconsistent with other visibility
filters as well as the current blocker system (as a blocker affects two
packages) and be more complicated to implement.</p>
</div>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id13" id="rationale" name="rationale">Rationale</a></h1>
<p>An implementation of this proposal should make it easy for users wishing
to regulate their software without affecting those that don't.</p>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id14" id="reference-implementation" name="reference-implementation">Reference Implementation</a></h1>
<p>Available in portage svn repository under main/branches/license-masking</p>
</div>
<div class="section">
<h1><a class="toc-backref" href="#id15" id="backwards-compatibility" name="backwards-compatibility">Backwards Compatibility</a></h1>
<p>There should be no change to the user experience without the user
explicitly choosing to do so.  This mandates that the
configuration variable be named <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> as some users may
already have it set due to ebuilds using <tt class="docutils literal"><span class="pre">eutil.eclass</span></tt>'s
implementation.  It also mandates that the default <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> be
set to <tt class="docutils literal"><span class="pre">&#64;NON-MUST-HAVE-READ</span></tt> in the main gentoo repository as implementations
are not required to provide an internal default.</p>

319	genone	1.6	<p>Currently, every ebuild in the main gentoo repository is required to have a
320			valid LICENSE entry. However, the syntax of this entry is not officially
321	g2boojum	1.4	defined and the entry itself is only used when outputting package
322	g2boojum	1.1	details.</p>
323			</div>

326	genone	1.5	<p>Repoman has been updated to check for the LICENSE syntax.
327			A development portage branch with support for ACCEPT_LICENSE

331			<h1><a class="toc-backref" href="#id7" id="motivation" name="motivation">Motivation</a></h1>
332			<p>Many users wish to regulate the software they install with regards to
333			licenses for various reasons <a class="footnote-reference" href="#id3" id="id1" name="id1">[1]</a>. Some want a system free of any
334			software that is not OSI-approved; others are simply curious as to what
335	g2boojum	1.1	licenses they are implicitly accepting.</p>
336	g2boojum	1.4	<p>Furthermore, some software requires that a user interactively accept its
337			license for its author's to consider it legally binding. This is
338			currently implemented using <tt class="docutils literal"><span class="pre">eutils.eclass</span></tt>.</p>
339			</div>
340			<div class="section">
341			<h1><a class="toc-backref" href="#id8" id="specification" name="specification">Specification</a></h1>
342			<div class="section">
343			<h2><a class="toc-backref" href="#id9" id="ebuild-license-variable" name="ebuild-license-variable">Ebuild LICENSE Variable</a></h2>
344			<p>Most ebuilds are for software which is released under a single license.
345			In these cases, the current LICENSE variable can remain as is. For
346	g2boojum	1.1	example:</p>
347			<pre class="literal-block">
348			LICENSE="single-license"
349			</pre>
350	g2boojum	1.4	<p>However, there are several ebuilds for software which is released under
351			several licenses, of which the user must accept one, some or all <a class="footnote-reference" href="#id4" id="id2" name="id2">[2]</a>.
352			To complicate this, some ebuilds include optional components which fall
353	g2boojum	1.1	under a different license.</p>
354	g2boojum	1.4	<p>To accomodate these cases, LICENSE syntax should accomodate all
355			functionality offered by a DEPEND string. To keep things simple, this
356	g2boojum	1.1	GLEP proposes that the syntax be identical. For example:</p>
357			<pre class="literal-block">
358	g2boojum	1.2	LICENSE="mandatory-license
359			\|\| ( choosable-licence1 chooseable-license-2 )
360	g2boojum	1.1	useflag? ( optional-component-license )"
361			</pre>
362	genone	1.6	<p>License names may contain [a-zA-Z0-9] (english alphanumeric characters),
363			_ (underscore), - (dash), . (dot) and + (plus sign).</p>
364	g2boojum	1.1	</div>
365	g2boojum	1.4	<div class="section">
366			<h2><a class="toc-backref" href="#id10" id="license-groups" name="license-groups">License Groups</a></h2>
367			<p>Almost all users are willing to install any software that is
368			FSF-approved. Other users are willing to install any software and
369	genone	1.6	implicitly accept its license. To this end, implementations will also
370			need to handle grouping of licenses.</p>
371	g2boojum	1.4	<p>At a minimum, there needs to be the groups <tt class="docutils literal"><span class="pre">GPL-COMPATIBLE</span></tt>,
372	genone	1.7	<tt class="docutils literal"><span class="pre">FSF-APPROVED</span></tt>, <tt class="docutils literal"><span class="pre">OSI-APPROVED</span></tt> and <tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt>.
373			<tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt> licenses are those that don't require manual
374	g2boojum	1.4	acceptance for to be considered legally binding. This is the current
375	g2boojum	1.2	behaviour of portage.</p>
376	genone	1.5	<p>These groups are defined in a new file <tt class="docutils literal"><span class="pre">license_groups</span></tt> in
377			the <tt class="docutils literal"><span class="pre">profiles</span></tt> subdirectory of the tree (or overlays).
378	genone	1.6	Details of handling groups defined in overlays is implementation dependent.</p>
379			<p>The format of this file is</p>
380	genone	1.5	<pre class="literal-block">
381			<groupname> <license1> <license2> ... <licenseN>
382			</pre>
383			<p>Also any line starting with # is ignored and may be used for comments.
384	genone	1.6	Group names use the same syntax as normal license names. Also license groups
385			may contain other groups.
386	genone	1.5	License groups may not contain negated elements, so a group</p>
387			<pre class="literal-block">
388			mygroup foo -bar -bla
389			</pre>
390			<p>is illegal.</p>
391	g2boojum	1.1	</div>
392	g2boojum	1.4	<div class="section">
393			<h2><a class="toc-backref" href="#id11" id="accept-license" name="accept-license">ACCEPT_LICENSE</a></h2>
394			<p>This GLEP proposes that a user be able to explicitly accept or decline
395			licenses by editing a new variable <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> in
396			<tt class="docutils literal"><span class="pre">/etc/make.conf</span></tt>. Again, to keep things simple, the syntax should be
397	g2boojum	1.1	similar to that of other incrementals. For example:</p>
398			<pre class="literal-block">
399			ACCEPT_LICENSE="-* accepted-license -declined-license"
400			</pre>
401	g2boojum	1.4	<p>As an extension, <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> must also support <a class="reference" href="#license-groups">license groups</a>.
402			This GLEP proposes that the license group be prepended by the special
403			character "<tt class="docutils literal"><span class="pre">@</span></tt>". For example:</p>
404	g2boojum	1.1	<pre class="literal-block">
405	g2boojum	1.2	ACCEPT_LICENSE="-* @FSF-APPROVED"
406	g2boojum	1.1	</pre>
407	genone	1.5	<p>License groups may be negated with the result that all elements of that group
408			are also negated.</p>
409	genone	1.6	<p>Portage will also offer a package.license facility to offer this functionality
410			on a per-package base (analog to package.keywords), other implementations may
411			implement such a facility differently or not at all.</p>

414	genone	1.6	<h2><a class="toc-backref" href="#id12" id="behaviour" name="behaviour">Behaviour</a></h2>
415	genone	1.5	<p>Unaccepted licenses will be treated like any other masked package, that is
416	genone	1.6	the user interface of an implementation will display a message listing any

419	genone	1.5	<p>Past versions of this document proposed to handle license-masked packages
420			like blockers, but this would be inconsistent with other visibility
