* thunderbird-filters-convertor.pl

  WHAT IT DOES
	This perl script converts Thunderbird filtering rules into Claws Mail
	filtering rules. It can be run several times, once for each filter
	configuration file in Thunderbird.

  HOW TO USE IT
	The script takes 3 arguments:

	--tbird-file=PATH TO FILE	The full path to the file to be converted
	--mailbox-name=NAME		The name of the Claws Mail mailbox
	--account-name=NAME		The name of the account to be used (optional)	

	--tbird-file must point to the Thunderbird filter file (msgFilterRules.dat)
	that you want to convert, it must contain the full path to the file.
	--mailbox-name should be given the name of your mailbox in Claws Mail, e.g.
	if the top-level folder is 'Mailbox (MH)' then this option should be
	'Mailbox'.
	--account-name is optional, only needed if you are creating account-specific
	rules. This is the name of your account in Claws Mail, which should
	correspond to an account that you had in Thunderbird, e.g. the acount whose
	rules you are converting.

	This script presumes that your folder hierarchy in Claws Mail matches the
	one that you had in Thunderbird. If you used the tbird2claws.py script to
	convert your Thunderbird mailbox, then the folder hierarchy should match.

	If the Claws Mail filtering configuration file (matcherrc) does not exist,
	the script will create it; if it does exist, the newly converted rules will
	be appended to it.
