319     <p>Currently, every ebuild in the portage tree is required to have a valid
320     LICENSE entry. However, the syntax of this entry is not officially
321     defined and the entry itself is only used when outputting package
322 g2boojum 1.1 details.</p>
323     </div>
324 g2boojum 1.4 <div class="section">
325     <h1><a class="toc-backref" href="#id6" id="status-update" name="status-update">Status Update</a></h1>
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
328     and license groups exists.</p>
329 g2boojum 1.3 </div>
330 g2boojum 1.4 <div class="section">
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=&quot;single-license&quot;
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=&quot;mandatory-license
359     || ( choosable-licence1 chooseable-license-2 )
360 g2boojum 1.1 useflag? ( optional-component-license )&quot;
361     </pre>
362     </div>
363 g2boojum 1.4 <div class="section">
364     <h2><a class="toc-backref" href="#id10" id="license-groups" name="license-groups">License Groups</a></h2>
365     <p>Almost all users are willing to install any software that is
366     FSF-approved. Other users are willing to install any software and
367     implicitly accept its license. To this end, portage will also need to
368 g2boojum 1.1 handle grouping of licenses.</p>
369 g2boojum 1.4 <p>At a minimum, there needs to be the groups <tt class="docutils literal"><span class="pre">GPL-COMPATIBLE</span></tt>,
370     <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-INTERACTIVE</span></tt>.
371     <tt class="docutils literal"><span class="pre">NON-INTERACTIVE</span></tt> licenses are those that don't require interactive
372     acceptance for to be considered legally binding. This is the current
373 g2boojum 1.2 behaviour of portage.</p>
374 genone 1.5 <p>These groups are defined in a new file <tt class="docutils literal"><span class="pre">license_groups</span></tt> in
375     the <tt class="docutils literal"><span class="pre">profiles</span></tt> subdirectory of the tree (or overlays).
376     The format of this file is</p>
377     <pre class="literal-block">
378     &lt;groupname&gt; &lt;license1&gt; &lt;license2&gt; ... &lt;licenseN&gt;
379     </pre>
380     <p>Also any line starting with # is ignored and may be used for comments.
381     License groups may not contain negated elements, so a group</p>
382     <pre class="literal-block">
383     mygroup foo -bar -bla
384     </pre>
385     <p>is illegal.</p>
386 g2boojum 1.1 </div>
387 g2boojum 1.4 <div class="section">
388     <h2><a class="toc-backref" href="#id11" id="accept-license" name="accept-license">ACCEPT_LICENSE</a></h2>
389     <p>This GLEP proposes that a user be able to explicitly accept or decline
390     licenses by editing a new variable <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> in
391     <tt class="docutils literal"><span class="pre">/etc/make.conf</span></tt>. Again, to keep things simple, the syntax should be
392 g2boojum 1.1 similar to that of other incrementals. For example:</p>
393     <pre class="literal-block">
394     ACCEPT_LICENSE=&quot;-* accepted-license -declined-license&quot;
395     </pre>
396 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>.
397     This GLEP proposes that the license group be prepended by the special
398     character &quot;<tt class="docutils literal"><span class="pre">&#64;</span></tt>&quot;. For example:</p>
399 g2boojum 1.1 <pre class="literal-block">
400 g2boojum 1.2 ACCEPT_LICENSE=&quot;-* &#64;FSF-APPROVED&quot;
401 g2boojum 1.1 </pre>

408     emerge will display a message listing any license that has to be accepted
409     before the package can be merged with a pointer to the exact license text.</p>
410     <p>Past versions of this document proposed to handle license-masked packages
411     like blockers, but this would be inconsistent with other visibility
412     filters as well as the current blocker system (as a blocker affects two
413     packages) and be more complicated to implement.</p>
