library

I came across this PL/SQL page today which has pointers to a lot of interesting stuff you can do with PL/SQL.

From the page:
"This library is a collection of various utility packages for PL/SQL, as well as links to useful libraries hosted and maintained elsewhere."

http://code.google.com/p/plsql-utils/

It includes a lot of things I never really figured I would need to do in PL/SQL, but it is nice to see someone is thinking of it. If you have any libraries to share, please contact the maintainers of the page.
