A few Sympa developers prefer to reformat source files casually using
automated tool, perltidy by Steve Hancock.

To get perltidy, install Perl-Tidy CPAN module or corresponding package
(if you are using package management system such as RPM, *BSD ports etc.).

dot.perltidyrc is the perltidy configuration file currently used to reformat
Sympa sources.  To use this file, copy it to your home directory renaming it
to ".perltidyrc", and run:

  perltidy -it=2 source_to_be_reformatted

and so on.  To know more about perltidy, run:

  perltidy -h

or visit The Perltidy Home Page:

  http://perltidy.sourceforge.net/
