A release assembler for Erlang.

Relx assembles releases for an Erlang/OTP release. Given a release specification and a list of directories in which to search for OTP applications it will generate a release output. That output depends heavily on what plugins available and what options are defined, but usually it is simply a well configured release directory.

The release-specification-file is optional but otherwise contains additional specification information for releases.
