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.
