If they use absolute paths embedded in code, they are poorly written
scripts, IMHO. The number of days I've wasted over the years dealing
with that kind of idiocy is more than I can remember.

Thank you, you make my point :) You can do this with Dirvish, but it
does NOT use absolute paths in the code. dirvish-runall reads
configuration, either from a file or from the command line and uses that
to determine where to find dirvish. Only if you don't tell it, does it
default to using the environment path. And even then, you can set that
path in the shell prior to calling dirvish-runall. No absolute paths in
the code.
