=head1 NAME

htmlclean - a small script to clean up existing HTML

=head1 SYNOPSIS

B<htmlclean [-v] [-V] file1 [file2 file3 ...]>

=head1 DESCRIPTION

This program provides a command-line interface to the HTML::Clean
module, which can help you to provide more compatible, smaller HTML
files at the expense of reducing the human readability of the HTML
code.  In some cases you may be able to reduce the size of your HTML
by up to 50%!

The HTML::Clean library provides a number of features that improve your
HTML for browsing and serving:

B<htmlclean> passes each file given on the command line to the library
and writes out the new HTML according to the specified options.  The
default is to create a backup file and replace the file with cleaned HTML.

=over 6

=item Removing whitespace, Comments and other useless or redundant constructs

=item Insuring that font tags work across multiple operating systems

For full details see the documentations for L<HTML::Clean> itself.
