Subject: Restructure .bashrc.d for prefix-ordered mass sourcing.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ebe05f993b872baaa01c74b62f6c16da2e258deb;p=dotfiles-public.git

Restructure .bashrc.d for prefix-ordered mass sourcing.

Inspired by Gentoo's setup of /etc/env.d, /etc/profile.d, etc.
