NAME

       matcherrc2perlfilter -- Conversion of matcherrc rules to perl

DESCRIPTION

       This script converts matcherrc filtering rules into perl_filter rules for usage with the claws-mail-perl-filter plugin of the Claws Mail
       mailer.

USAGE

       matcherrc2perlfilter

       No arguments required. Conversion is done for current user only.

FILES

       $HOME/.claws-mail/matcherrc
	 Input file where standard filtering rules lie.

       $HOME/.claws-mail/perl_filter
	 Output file written by this script. Converted rules are appended if the file already exists, so be careful when running the script more
	 than once.

BUGS

       This conversion script doesn't produce nice Perl code and is just intended to get you started. If you choose to use the Perl plugin,
       consider rewriting your rules.
