NAME

       rel - Release resource file

DESCRIPTION

       The  release  resource  file specifies which applications are 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 should 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() is the name of the release.

         * Vsn = string() is the version of the release.

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

         * Application = atom() is the name of an application included in the release.

         * AppVsn = string() is the version of an application included in the release.

         * Type  =  permanent | transient | temporary | load | none is the start type of an application included
           in the release.

           If Type = permanent | transient | temporary, the application  will  be  loaded  and  started  in  the
           corresponding  way,  see  application(3erl).  If Type = load, the application will only be loaded. If
           Type = none, the application will be neither loaded nor started, although the code  for  its  modules
           will be loaded. Defaults to permanent

         * IncApps  =  [atom()]  is  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.
