Re: [gentoo-dev] making metadata.xml pay off and removing pkg_postinst crud

1. The XML tag shouldn't really be called postinst. Something like <howto> or 
<instructions> looks better for this purpose.
2. Some packages may have different instructions based on the version 
installed. metadata.xml is the same for all versions of a package.

Alternatively, why not add a pkg_instructions function and have 'emerge help 
...' or 'ebuild ... instructions' run that? It could be run after 
pkg_postinst of a normal emerge, also.
