I don't get your point. What you specify is equivalent to what I
already have in my .bashrc... unless your point is specifying a
variable which is sure to be *at least* a relative path to the script.
Well... that's not even sure if the DEVEL_BASHRC directory has been
put in the proper place within the user's PATH or if the user happened
to install it in his $HOME directory, then DEVEL_BASHRC could possibly
simply be defined as DEVEL_BASHRC=bashrc and the script would still
have no clue where itself was.
