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.
