These are the functions defined in the plugins functions .h file.

The page for each function is initially generated from that .h file - but any changes made here won't be overwritten, so feel free to correct or add to any of the information here.

Some of the identifiers start with the underscore character and MediaWiki doesn't always appreciate it. You need to be aware that Wiki sometimes translates the underscore character to a space.
