# imerge - fastest way to get the description from many ebuilds simultaniously
#
# usage: cd /usr/portage/any-category && imerge filename
#    or: imerge /usr/portage/any-category/filename
#
# filename can be any shell regex but metachars like '*' have to be escaped. 
#
# to get all windowmaker plugins you'd do:
# imerge /usr/portage/x11-plugins/wm\*
#
# have phun ;)
