Hi Graham,

While not addressing the libraries issue, I do have a habit for naming
stacks that I find very useful. Each project gets a prefix and all the
stacks in that project have stacksNames starting with that prefix e.g.
a current project is called "Temperature Monitor" so the stacks are
all called "tm..." - tmPrefs, tmAbout, tmHelp etc.

This is really useful when you want more than one project open as
nearly all my projects have a Help stacks, a Prefs stacks and an About
stack among the list.

For your library stacks, again you want to make sure you will have mo
confilcts when loading them in to any of your projects, so I suggest
something similar e.g. gsLibFiles, gsLibGraphics etc. Remember that
you may want to use other peoples' libraries at some stage, so adding
an identifier unique to you is a good idea.

Have a look at the Rev Interoperability Project guidelines
<http://www.revjournal.com/features/rip/index.html> for some more
ideas along these lines.

Cheers,
Sarah
