Auto-renames all TV episodes in the current directory using tvnamer. File
names have to already be in a Kodi-compatible sNNeNN, NNxNN or equivalent
format.

Tvnamer will ask a few interactive questions on launch in order to keep the
mess-up potential minimal.

If no parameters are given, the series name is derived from the directory
name. A single parameter is interpreted as a series name. If tvnamer is unable
to find a series or a specific dub but you know it has an entry in
thetvdb.com, you can provide the numeric series ID as a second parameter.

To see non-English dubs in the first place, you may in some cases have to
create a configuration file using 'tvnamer -s' and set the language code. This
file, provided it exists, is expected in the following location:

$configfile
