318     <h1><a class="toc-backref" href="#id5" id="abstract" name="abstract">Abstract</a></h1>
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 g2boojum 1.3 <p>Repoman has been updated to check for the LICENSE syntax.</p>
327     </div>
328 g2boojum 1.4 <div class="section">
329     <h1><a class="toc-backref" href="#id7" id="motivation" name="motivation">Motivation</a></h1>
330     <p>Many users wish to regulate the software they install with regards to
331     licenses for various reasons <a class="footnote-reference" href="#id3" id="id1" name="id1">[1]</a>. Some want a system free of any
332     software that is not OSI-approved; others are simply curious as to what
333 g2boojum 1.1 licenses they are implicitly accepting.</p>
334 g2boojum 1.4 <p>Furthermore, some software requires that a user interactively accept its
335     license for its author's to consider it legally binding. This is
336     currently implemented using <tt class="docutils literal"><span class="pre">eutils.eclass</span></tt>.</p>
337     </div>
338     <div class="section">
339     <h1><a class="toc-backref" href="#id8" id="specification" name="specification">Specification</a></h1>
340     <div class="section">
341     <h2><a class="toc-backref" href="#id9" id="ebuild-license-variable" name="ebuild-license-variable">Ebuild LICENSE Variable</a></h2>
342     <p>Most ebuilds are for software which is released under a single license.
343     In these cases, the current LICENSE variable can remain as is. For
344 g2boojum 1.1 example:</p>
345     <pre class="literal-block">
346     LICENSE=&quot;single-license&quot;
347     </pre>
348 g2boojum 1.4 <p>However, there are several ebuilds for software which is released under
349     several licenses, of which the user must accept one, some or all <a class="footnote-reference" href="#id4" id="id2" name="id2">[2]</a>.
350     To complicate this, some ebuilds include optional components which fall
351 g2boojum 1.1 under a different license.</p>
352 g2boojum 1.4 <p>To accomodate these cases, LICENSE syntax should accomodate all
353     functionality offered by a DEPEND string. To keep things simple, this
354 g2boojum 1.1 GLEP proposes that the syntax be identical. For example:</p>
355     <pre class="literal-block">
356 g2boojum 1.2 LICENSE=&quot;mandatory-license
357     || ( choosable-licence1 chooseable-license-2 )
358 g2boojum 1.1 useflag? ( optional-component-license )&quot;
359     </pre>
360     </div>
361 g2boojum 1.4 <div class="section">
362     <h2><a class="toc-backref" href="#id10" id="license-groups" name="license-groups">License Groups</a></h2>
363     <p>Almost all users are willing to install any software that is
364     FSF-approved. Other users are willing to install any software and
365     implicitly accept its license. To this end, portage will also need to
366 g2boojum 1.1 handle grouping of licenses.</p>
367 g2boojum 1.4 <p>At a minimum, there needs to be the groups <tt class="docutils literal"><span class="pre">GPL-COMPATIBLE</span></tt>,
368     <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>.
369     <tt class="docutils literal"><span class="pre">NON-INTERACTIVE</span></tt> licenses are those that don't require interactive
370     acceptance for to be considered legally binding. This is the current
371 g2boojum 1.2 behaviour of portage.</p>
372 g2boojum 1.1 </div>
373 g2boojum 1.4 <div class="section">
374     <h2><a class="toc-backref" href="#id11" id="accept-license" name="accept-license">ACCEPT_LICENSE</a></h2>
375     <p>This GLEP proposes that a user be able to explicitly accept or decline
376     licenses by editing a new variable <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> in
377     <tt class="docutils literal"><span class="pre">/etc/make.conf</span></tt>. Again, to keep things simple, the syntax should be
378 g2boojum 1.1 similar to that of other incrementals. For example:</p>
379     <pre class="literal-block">
380     ACCEPT_LICENSE=&quot;-* accepted-license -declined-license&quot;
381     </pre>
382 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>.
383     This GLEP proposes that the license group be prepended by the special
384     character &quot;<tt class="docutils literal"><span class="pre">&#64;</span></tt>&quot;. For example:</p>
385 g2boojum 1.1 <pre class="literal-block">
386 g2boojum 1.2 ACCEPT_LICENSE=&quot;-* &#64;FSF-APPROVED&quot;
387 g2boojum 1.1 </pre>
388     </div>
389 g2boojum 1.4 <div class="section">
390     <h2><a class="toc-backref" href="#id12" id="emerge-behaviour" name="emerge-behaviour">Emerge Behaviour</a></h2>
391     <p>At a minimum, emerge must handle unaccepted licenses the same way that
392     it handles blockers. That is, with the --pretend flag the
393     not-yet-accepted license should be listed in the output. Without the
394 g2boojum 1.1 --pretend flag, emerge should stop before any software is installed.</p>
395 g2boojum 1.4 <p>This GLEP proposes that, unlike blockers, dependencies for software
396     should be checked regardless of license acceptance. Doing so will allow
397     the user to review all necessary licenses before initiating an actual
398 g2boojum 1.1 emerge.</p>
399 g2boojum 1.4 <p>It is also proposed that the --ask option will display an unaccepted
400     license and ask for acceptance, but not update any configuration files
401     at this stage. Finally, the --verbose option should also list the
402 g2boojum 1.1 licenses accepted for each package.</p>
403     </div>
404     </div>
405 g2boojum 1.4 <div class="section">
406     <h1><a class="toc-backref" href="#id13" id="rationale" name="rationale">Rationale</a></h1>
407     <p>An implementation of this proposal should make it easy for users wishing
408 g2boojum 1.1 to regulate their software without affecting those that don't.</p>
409     </div>
410 g2boojum 1.4 <div class="section">

415     <h1><a class="toc-backref" href="#id15" id="backwards-compatibility" name="backwards-compatibility">Backwards Compatibility</a></h1>
416     <p>There should be no change to the user experience without the user
417     explicitly choosing to do so. This mandates that the
418     configuration variable be named <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> as some users may
419     already have it set due to ebuilds using <tt class="docutils literal"><span class="pre">eutil.eclass</span></tt>'s
420     implementation. It also mandates that the default <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> be
