NAME

       rel - Release resource file

DESCRIPTION

       The  release resource file specifies which applications are included in a release (system)
       based on Erlang/OTP.

       This file is used by the functions in systools when  generating  start  scripts  (.script,
       .boot) and release upgrade files (relup).

FILE SYNTAX

       The release resource file is to be called Name.rel.

       The  .rel  file  contains one single Erlang term, which is called a release specification.
       The file has the following syntax:

       {release, {RelName,Vsn}, {erts, EVsn},
         [{Application, AppVsn} |
          {Application, AppVsn, Type} |
          {Application, AppVsn, IncApps} |
          {Application, AppVsn, Type, IncApps}]}.

         RelName = string():
           Release name.

         Vsn = string():
           Release version.

         EVsn = string():
           ERTS version the release is intended for.

         Application = atom():
           Name of an application included in the release.

         AppVsn = string():
           Version of an application included in the release.

         Type = permanent | transient | temporary | load | none:
           Start type of an application included in the release.

           If Type = permanent | transient | temporary, the application is loaded and started  in
           the corresponding way, see application(3erl).

           If Type = load, the application is only loaded.

           If  Type  = none, the application is not loaded and not started, although the code for
           its modules is loaded.

           Defaults to permanent

         IncApps = [atom()]:
           A list of applications that are included by an application included  in  the  release.
           The  list  must  be a subset of the included applications specified in the application
           resource file (Application.app) and overrides this value. Defaults to the  same  value
           as in the application resource file.

   Note:
       The list of applications must contain the Kernel and STDLIB applications.
