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. hth, James
