There is no much to comment, since it is a small short-lived script.
But there are some notes that are correct for any FVWM module written in
Perl, so this may be useful to all Perl writers.
First, you may replace all 3 "use Some::Module;" lines with one:
use FVWM::Module::Toolkit qw( File::Find Image::Magick );
This loads the specified perl classes, or shows a nice error window if
any of them are not installed on the user's system and exits.
Optionally, you may replace "new FVWM::Module" with "new
FVWM::Module::Toolkit", the first class writes all debug, errors and
messages to standard output, the second opens dialog windows instead,
this may be more user friendly or more annoying, depending on a module.
Run "fvwm-perllib man FVWM::Tracker::PageInfo" to see how to find the
screen dimensions in your module.
Regards,
Mikhael.
