Subject: Generalize the sed -> gsed wrapper script so that it's
X-Git-Tag: v2.1.4~102
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=084d2755b44f86dab83ac2cbd3256c6ee7ef1bbe;p=portage.git

Generalize the sed -> gsed wrapper script so that it's
possible to create awk, make, and patch symlinks that
behave analogously. These symlinks will make
it unnecessary for default-bsd profiles to define
profile.bashrc aliases for these commands.
