-/**
- * Temporary File Filter Plugin
- *
- * The purpose of this filter is to intercept some of the garbage files
- * operation systems and applications tend to generate when mounting
- * a WebDAV share as a disk.
- *
- * It will intercept these files and place them in a separate directory.
- * these files are not deleted automatically, so it is adviceable to
- * delete these after they are not accessed for 24 hours.
- *
- * Currently it supports:
- * * OS/X style resource forks and .DS_Store
- * * desktop.ini and Thumbs.db (windows)
- * * .*.swp (vim temporary files)
- * * .dat.* (smultron temporary files)
- *
- * Additional patterns can be added, by adding on to the
- * temporaryFilePatterns property.
