Perltidy is a Perl script which indents and reformats Perl
 scripts to make them easier to read.
 .
 The formatting can be controlled with command line parameters.
 The default parameter settings approximately follow the
 suggestions in the Perl Style Guide.
 .
 Perltidy can also generate formatted HTML output from POD, and can
 even generate colored output in HTML for scripts. See examples at
