Though you might be able to share collections directories by setting the
"PLTCOLLECTS" environment variable or using symlinks, that can turn into
a headache.  Also, the collections directories contain compiled ".zo"
files that are not necessarily compatible between different PLT
versions.

What might be easiest and most reliable is to keep all your ".plt" files
in a directory outside of your installed PLT directory trees, then
execute "setup-plt *.plt" every time you update a PLT installation.
It doesn't take long to run.

Additionally, if every time you update a PLT installation you have it
install a clean "collects" tree, you avoid accumulating unique cruft in
those trees that would create reproducibility QA problems.
