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 applica-
	   tion(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 empty list.

   Note:
       The list of applications must contain the kernel and stdlib applications.
