To support OTP release upgrades I have added support for building upgrade packages. Support for this is included in the rebar_upgrade module, specifically generate_upgrade/2. It requires one variable to be set on the command line 'previous_release' which is the absolute path or relative path from 'rel/' to the previous release one is upgrading from. Running an upgrade will create the needed files, including a relup and result in a tarball containing the upgrade being written to 'rel/'. When done it cleans up the temporary files systools created. Usage: $ rebar generate-upgrade previous_release=/path/to/old/version This also includes a dummy application that can be used to test upgrades as well as an example. Special thanks to Daniel Reverri, Jesper Louis Andersen and Richard Jones for comments and patches.
