=head1 DESCRIPTION

Convert various kinds of mail folders to HTML, permitting them to be
read by a web browser.

Options:

=over 4

=item -cleanup =E<gt> BOOLEAN

(or C<-cleanup> or C<-nocleanup>) removes the directory before generating
the data.

=item -dest =E<gt> DIRECTORY

The output directory. When this option is not specified, the program will
try to create a sub-directory named C<mail2html> in the directory pointed
to by the environment variable TMPDIR or tmpdir, otherwise the output will
be in C</var/tmp> or C</tmp>.

=item -folderpage =E<gt> FILENAME

# DWC Hm... 2nd sentence doesn't make sense
The template which is used to create folder pages.  See the examples with
the distribution of this code for examples.

=item -help =E<gt> BOOLEAN

(or C<-help> or C<-?>) Print a brief help

=item -index =E<gt> FILENAME

The filename which the web server loads when the user specifies only the
name of the directory in a URL. This option is set to C<index.html> by
default.

=item -messagepage =E<gt> FILENAME

# DWC Hm... 2nd sentence doesn't make sense
The template which is used to create one page per message.
See the examples with the distribution of this code for examples.

=item -recurse =E<gt> BOOLEAN

(or C<-recurse> or <-norecurse>) Recurse through subfolders.  By default,
recursive production is enabled.

=item -src =E<gt> FILE | DIRECTORY

Start with the folder(-directory) which can be found at the specified
location.  The type of folder is auto-detected.  By default, the contents
of the directory specified by the C<MAIL> or C<mail> environment variable
are used. If these variables are not defined, C<HOME> and C<home> are
checked for a sub-directory named C<Mail>.  If these are unsuccessful as
well, the current directory is used.

=item -verbose =E<gt> BOOLEAN

(or C<-verbose> or C<-noverbose>) Be verbose about the progress of the
program.  This is especially useful for debugging purposes.
