=head1 SYNOPSIS
-pod2text [B<-aclst>] [B<-i> I<indent>] [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.
-
-B<pod2text> defaults to trying to use Pod::Text::Termcap if STDOUT is a tty.
-To explicitly say not to attempt termcap escape sequences, use
-B<--notermcap>.
+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
+I<quotes> is a single character, it is used as both the left and right
+quote; if I<quotes> is two characters, the first character is used as the
+left quote and the second as the right quoted; and if I<quotes> is four
+characters, the first two are used as the left quote and the second two as
+the right quote.
+
+I<quotes> may also be set to the special value C<none>, in which case no
+quote marks are added around CE<lt>> text.
+
=item B<-s>, B<--sentence>
Assume each sentence ends with two spaces and try to preserve that spacing.
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
sequences for the terminal from termcap, and use that information in
formatting the output. Output will be wrapped at two columns less than the
width of your terminal device. Using this option requires that your system
-have a termcap file somewhere where Term::Cap can find it. With this
-option, the output of B<pod2text> will contain terminal control sequences
-for your current terminal type.
