4) # This script permit to convert Thunderbird mail filters to SOGo
5) # filters. It take as input msgFilterRules.dat path (-f parameter),
6) # parse file and try to convert filters in SOGo equivalent. Some 
7) # filters conditions or actions can't be converted as SOGo filters,
8) # so warning or critical messages will be inform you of possible
9) # conversions problems. Output is in JSON format. By default, JSON
10) # string is write and stdout but you could provide with -o parameter
11) # a file path where JSON have to be write.
12) #
13) # To know how to load JSON in SOGo, see README file.
