=head1 SYNOPSIS
-pod2text [B<-aclst>] [B<-i> I<indent>] [B<-q> I<quotes>] [B<-w> I<width>]
-[I<input> [I<output>]]
+pod2text [B<-aclost>] [B<--code>] [B<-i> I<indent>] S<[B<-q> I<quotes>]>
+ [B<--stderr>] S<[B<-w> I<width>]> [I<input> [I<output> ...]]
pod2text B<-h>
either termcap sequences or ANSI color escape sequences to format the text.
I<input> is the file to read for POD source (the POD can be embedded in
-code). If I<input> isn't given, it defaults to STDIN. I<output>, if given,
-is the file to which to write the formatted output. If I<output> isn't
-given, the formatted output is written to STDOUT.
+code). If I<input> isn't given, it defaults to C<STDIN>. I<output>, if
+given, is the file to which to write the formatted output. If I<output>
+isn't given, the formatted output is written to C<STDOUT>. Several POD
+files can be processed in the same B<pod2text> invocation (saving module
+load and compile times) by providing multiple pairs of I<input> and
+I<output> files on the command line.
=head1 OPTIONS
Use an alternate output format that, among other things, uses a different
heading style and marks C<=item> entries with a colon in the left margin.
+=item B<--code>
+
+Include any non-POD text from the input file in the output as well. Useful
+for viewing code documented with POD blocks with the POD rendered and the
+code left intact.
+
=item B<-c>, B<--color>
Format the output with ANSI color escape sequences. Using this option
because this is the expected formatting for manual pages; if you're
formatting arbitrary text documents, using this option is recommended.
+=item B<-m> I<width>, B<--left-margin>=I<width>, B<--margin>=I<width>
+
+The width of the left margin in spaces. Defaults to 0. This is the margin
+for all text, including headings, not the amount by which regular text is
+indented; for the latter, see B<-i> option.
+
+=item B<-o>, B<--overstrike>
+
+Format the output with overstrike printing. Bold text is rendered as
+character, backspace, character. Italics and file names are rendered as
+underscore, backspace, character. Many pagers, such as B<less>, know how
+to convert this to bold or underlined text.
+
=item B<-q> I<quotes>, B<--quotes>=I<quotes>
Sets the quote marks used to surround CE<lt>> text to I<quotes>. If
Without this option, all consecutive whitespace in non-verbatim paragraphs
is compressed into a single space.
+=item B<--stderr>
+
+By default, B<pod2text> puts any errors detected in the POD input in a POD
+ERRORS section in the output manual page. If B<--stderr> is given, errors
+are sent to standard error instead and the POD ERRORS section is
+suppressed.
+
=item B<-t>, B<--termcap>
Try to determine the width of the screen and the bold and underline
