Detailed Description

Class to represent a local file in the wiki's own database.

Provides methods to retrieve paths (physical, logical, URL), to generate image thumbnails or for uploading.

Note that only the repo object knows what its file class is called. You should never name a file class explictly outside of the repo class. Instead use the repo's factory functions to generate file objects, for example:

RepoGroup::singleton()->getLocalRepo()->newFile( $title );

The convenience functions wfLocalFile() and wfFindFile() should be sufficient in most cases.
