[gentoo-portage-dev] [PATCH] Extra info about installed packages feature

[Jason Stubbs]

[-- Attachment #1: Type: text/plain, Size: 272 bytes --]

This patch is by swegener. It allows one to specify atoms after `emerge info` 
that will be matched to installed packages. Any installed packages found that 
have settings differing to the current settings will have those settings 
printed out along with the global info.
