+=head1 SYNOPSIS
+
+pod2text [B<-aclostu>] [B<--code>] [B<-i> I<indent>] S<[B<-q> I<quotes>]>
+ [B<--stderr>] S<[B<-w> I<width>]> [I<input> [I<output> ...]]
+

+
+=head1 DESCRIPTION
+
+B<pod2text> is a front-end for Pod::Text and its subclasses. It uses them
+to generate formatted ASCII text from POD source. It can optionally use
+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 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
+
+=over 4
+
+=item B<-a>, B<--alt>
+
+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
+requires that Term::ANSIColor be installed on your system.
+
+=item B<-i> I<indent>, B<--indent=>I<indent>
+
+Set the number of spaces to indent regular text, and the default indentation
+for C<=over> blocks. Defaults to 4 spaces if this option isn't given.
+
+=item B<-h>, B<--help>
+
+Print out usage information and exit.
+
+=item B<-l>, B<--loose>
+
+Print a blank line after a C<=head1> heading. Normally, no blank line is
+printed after C<=head1>, although one is still printed after C<=head2>,
+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 and requires that
+your system support termios. With this option, the output of B<pod2text>
+will contain terminal control sequences for your current terminal type.
+
+=item B<-u>, B<--utf8>
+
+By default, B<pod2text> tries to use the same output encoding as its input
+encoding (to be backward-compatible with older versions). This option
+says to instead force the output encoding to UTF-8.
+
+Be aware that, when using this option, the input encoding of your POD
+source must be properly declared unless it is US-ASCII or Latin-1. POD
+input without an C<=encoding> command will be assumed to be in Latin-1,
+and if it's actually in UTF-8, the output will be double-encoded. See
+L<perlpod(1)> for more information on the C<=encoding> command.
+
+=item B<-w>, B<--width=>I<width>, B<->I<width>
+
+The column at which to wrap text on the right-hand side. Defaults to 76,
+unless B<-t> is given, in which case it's two columns less than the width of
+your terminal device.
+
+=back
+
+=head1 DIAGNOSTICS
+
+If B<pod2text> fails with errors, see L<Pod::Text> and L<Pod::Simple> for
+information about what those errors might mean. Internally, it can also
+produce the following diagnostics:
+
+=over 4
+
+=item -c (--color) requires Term::ANSIColor be installed
+
+(F) B<-c> or B<--color> were given, but Term::ANSIColor could not be
+loaded.
+
+=item Unknown option: %s
+
+(F) An unknown command line option was given.
+
+=back
+
+In addition, other L<Getopt::Long> error messages may result from invalid
+command-line options.
+
+=head1 ENVIRONMENT
+
+=over 4
+
+=item COLUMNS
+
+If B<-t> is given, B<pod2text> will take the current width of your screen
+from this environment variable, if available. It overrides terminal width
+information in TERMCAP.
+
+=item TERMCAP
+
+If B<-t> is given, B<pod2text> will use the contents of this environment
+variable if available to determine the correct formatting sequences for your
+current terminal device.
