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.
