I added this to root's .bashrc a long time ago:
# USE flag settings hack by Ciaran McCreesh:
explainuseflag(){ sed -ne "s,^\([^ ]*:\)\?$1 - ,,p" $(portageq
portdir)/profiles/use.{,local.}desc; }
alias ef="explainuseflag"
Then simply use the alias for a quick check to learn about all the different
uses of a given flag:
'ef graphite'
# ef graphite
Enable support for non-Roman fonts via media-gfx/graphite2
Enable support for non-Roman fonts via media-gfx/graphite2
Add support for the framework for loop optimizations based on a polyhedral
intermediate representation
Then drill down into the a specific package's use flag meaning, using the
aforementioned 'equery u' delineated by Albert.
