# Run rip-episodes over several directories. Arguments will be passed to
# rip-episodes. The episode number and season will be determined by the directory name.
# E.g.,

# ├── XFILES_S02E01-4
# ├── XFILES_S02E05-8
# ├── XFILES_S02E13-16
# ├── XFILES_S02E17-20
# ├── XFILES_S02E21-24
# └── XFILES_S02E9-12
#
# rip-all-episodes -e XFILES -p 'The X-Files'
# will rip files to ./The X-Files/The X-Files-S02E01.mkv etc.
