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.
