	That's what the .so files in /lib and /usr/lib are for.

	Start with "man dlopen" and go from there.

	Normally, you don't need to worry about explicity loading libraries
unless you are doing dynamic plugins.  Just linking against the dynamic
libraries is sufficient in most cases.

	There are several out there (Code Warrior?) but I have never
needed one and just find they get in the way, so I have no experience there.

	Check out freetype, <http://www.freetype.org>.
