NAME
rel - Release resource fileDESCRIPTION
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.
