This has several drawbacks: not only is it impossible to change any aspect of +Portage behaviour without verifying that nothing in the tree relies upon it, but if a new +package manager should appear it becomes impossible to fully support such an ill-defined +standard. +</p><!--l. 23--><p class="noindent" >This document aims to address both of these concerns by defining almost all aspects of what an +ebuild repository looks like, and how an ebuild is allowed to behave. Thus, both Portage and other +package managers can change aspects of their behaviour not defined here without worry of +incompatibilities with any particular repository. +</p><!--l. 28--><p class="noindent" > +</p> +<h3 class="sectionHead"><span class="titlemark">1.3 </span> <a + id="x1-80001.3"></a>Reporting Issues</h3> +<!--l. 30--><p class="noindent" >Issues (inaccuracies, wording problems, omissions etc.) in this document should be reported via +Gentoo Bugzilla using product <span +class="ecti-1000">Gentoo Hosted Projects</span>, component <span +class="ecti-1000">PMS/EAPI </span>and the default +assignee.
