[erlang-questions] Library lookup path

[Kevin A. Smith]

How do I tell Erlang to look in additional places for libraries? I've  
got a build script which builds a set of libraries and puts them in a  
directory named build. Each library gets its own subdirectory like so:  
build/foo-0.1, build/bar-0.1, etc. Right now, I'm symlinking these  
directories into $ROOT/lib so that Erlang can find them at runtime.  
What I'd really like to be able to do is pass erl a flag, like -pa/- 
pz, and tell it where to find these libs. Does something like this  
exist?

Thanks,
Kevin
