 7  ### 
 8  ## autosaves roll from 0-9 eg myfile.autosave, myfile.autosave1, myfile.autosave2...

10  ## To use just add 'import nukescripts.autosave' in your init.py

90  #nuke.removeAutoSaveFilter( onAutoSave ) 
91  #nuke.removeAutoSaveRestoreFilter( onAutoSaveRestore ) 
92  #nuke.removeAutoSaveDeleteFilter( onAutoSaveDelete )
