Command: Make me a library!
Response: Okay, you're a library.
Seriously, IDL libraries are more conceptual than technical.
Typically, one puts library routines into a single subdirectory in
one's IDL path. [ but that's not required. ]
Often, routines in the same library have names which begin with the
same prefix. [ but that's not required. And JD is not fond of that
technique. ]
Often, libraries are distributed as a single .zip or .tar.gz archive
file with several .pro files inside. [ but that's not required. ]
It is possible to package your library into a single IDL .sav file,
but I don't recommend that for several reasons. First, it's version
dependent. If you ever use a different version of IDL, you'll
probably have to re-make the .sav file. Second, you still need to
restore the .sav file, which is not straightforward to do
automatically.
In conclusion, just put your routines in their own subdirectory, call
them a library, and they will be one.
Yours,
Craig
