I just made a bunch of scripts to modify the kpse variables so when I start a latex
project it takes the system values and adds stuff to the front as well as back...
In theory anyway the system values can change and this is a transparent prepend.
or append.
The syntax IIRC was a bit different for normal paths ( something about descending into
subdirs ) but logic similar.

This is why I recommend using the standard personal TeX directory idea:
it saves having to edit paths that will get overwritten by a version update.
