Subject: Shortcut to setting PROFILE_HOME.
X-Git-Url: http://git.iain.cx/?a=commitdiff_plain;h=84e1a34d8cc3838b7666ba26f02648cdee4906c6;p=profile.git

Shortcut to setting PROFILE_HOME.

Allow sourcing .bash_profile directly to set up PROFILE_HOME.

A user can now simply run ``. /profile/path/.bash_profile'' instead of
``PROFILE_HOME=/profile/path; .  $PROFILE_HOME/.bash_profile'' to use
these scripts.
