**This module is deprecated!**
The subsystems installer factory provides support for subsystems to the [OSGI installer](/documentation/bundles/osgi-installer.html). The provisioning of artifacts is handled by installer providers like the file installer or the JCR installer.


## Subsystems
 	 
The subsystem file must end with ".esa" and the manifest must at least contain the subsystem symbolic name "Subsystem-SymbolicName" header.
