/*
|

examples for feature priorization:
|
||||
|
||||
# if multiple torrents are available, the torrent with most features of this list will be prioritized.
|
||||
# when a new torrent with more features is uploaded, it will replace the files of the old torrent.
|
||||
# that ensures availability of latest episodes but highest preferred quality on the long run
|
||||
#
|
||||
# This list is ordered by the separator '|'. Features within the same '|' block (separated by comma) get same priority.
|
||||
# the first '|' block is prioritized highest.
|
||||
#
|
||||
# '_' is a placeholder for all other features not directly mentioned in the list.
|
||||
# It can be used for a default priority. If not default priority is given, it will be set to 0.
|
||||
#
|
||||
# This example basically means:
|
||||
# torrents with japanese language have priority 3
|
||||
# torrents with english or german languages or subtitles in english or german have priority 2
|
||||
# torrents with any other languages or subtitles will have priority 1
|
||||
TORRENT_PRIORITIZED_FEATURES="sub:ja|lang:en,sub:en,lang:de,sub:de|lang:_,sub:_"
|
||||
|
||||
# torrents without these features will never be downloaded ('_' features not supported)-
|
||||
#
|
||||
# essential features will be parsed before prioritized features.
|
||||
# a feature cannot be both essential and prioritized.
|
||||
#
|
||||
# This example basically means: Only download torrents with japanese language and subtitles
|
||||
TORRENT_ESSENTIAL_FEATURES="lang:ja,1080p"
|
||||
|
||||
# complete feature list:
|
||||
# "lang:<lang_code>": language (audio)
|
||||
# "sub:<lang_code>": subtitles
|

# "1080p[:<bool>]": full hd resolution with optional bool flag

# "720p[:<bool>]": hd resolution
