[erlang-questions] How do I include a library across muiltple apps in a release?

[Mazen Harake]

You should do as you already suggested... make a library application. It 
is not overkill, it is good practice. If you add it to your rel-file and 
use OTP release handling with that then the library will always be part 
of your release. This is a good thing
