I'd like to announce the first official release of the Safe Function Call plugin (v1.0).
Safely call functions that may not be available (for example, from within a template, calling a function that is provided by a plugin that may be deactivated).
Visit its homepage at:
http://coffee2code.com/wp-plugins/safe-function-call/
Details, documentation, examples, and the download can be found there.
This plugin was released as part of 14 Days of Plugins (new plugin #5).
