STS Template Engine
The STS Template Engine, developed by Sunrise Telephone Systems is a universal template engine for Cocoa featuring its own macro language for conditional template expansion. Although it can be used for any kind of template expansion requirement, it was developed for the purpose of generating Asterisk configuration files from templates.
The STS Template Engine is released under the GPL version 2 as Objective-C source code for embedding into Cocoa or GNUstep applications. A download link and detailed documentation is at this link is delete for SPAM to porno webs.
