#To run: python tv_renamer.py <FULL PATH> <SHOWNAME> <SEASON #> <first episode # in folder>(Optional)
#The last param is in case you have multiple discs for a single season and rip each disc to a separate folder.

#This renames all the items in <FULL PATH> with the format: <SHOWNAME>.s<SEASONNUMBER>.eXX.extension
#The script assumes the items are already ordered within the folder however.
