Faxien provides Erlang/OTP package management. Faxien fetches packages from the remote repository and installs them on your local machine. Faxien also publishes packages located on your local hard disk into a remote repository.
Faxien deals with two distinct types of packages. The first is the OTP application which consists of src, ebin, etc... The second is an OTP release which is essentially a number of applications combined with configuration, .script and .boot files, and executable scripts. In brief a release is a standalone Erlang service of sorts.
