-=head1 NAME
-
-Clawsker - A Claws Mail Tweaker
-
-=head1 SYNOPSIS
-
-clawsker [options]
-
-=head1 DESCRIPTION
-
-Clawsker is an applet to edit the so called Claws Mail hidden preferences.
-
-Claws Mail is a fast, lightweight and feature-rich MUA with a high number 
-of configurable options. To keep the binary small and fast some of these 
-preferences which are not widely used are not provided with a graphical
-interface for inspection and/or modification.
-
-Users wanting to edit such preferences had to face raw editing of their 
-configuration files, now you can do it with a convenient GTK2 interface
-using Clawsker.
-
-=head1 OPTIONS
-
---help
-       Shows a brief help screen.
-
---version
-       Show information about program, Claws Mail and Perl-GTK versions.
-
---verbose
-       Tells more on the standard output.
-
---alternate-config-dir <dir>
-       Uses <dir> as Claws Mail configuration dir.
-
---clawsrc <file>
-       Uses <file> as Claws Mail resource configuration file. This sets
-       the full file name overriding any previous setting.
-
-Multiple options are allowed, although only the last one has effect. Weird
-option specifications may produce weird results (but otherwise correct).
-       
-=head1 LIMITATIONS
-
-A running Claws Mail cannot be detected if using the --clawsrc option because
-the directory is not assumed to be a Claws Mail configuration dir. If that is 
-the case use the --alternate-config-dir option instead.
