+=head1 NAME
+
+pod2text - Convert POD data to formatted ASCII text
+
+=head1 SYNOPSIS
+
+pod2text [B<-aclst>] [B<-i> I<indent>] [B<-w> I<width>] [I<input> [I<output>]]
+
+pod2text B<-h>
+
+=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 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.
+
+=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<-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<-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>.
+This is the default because it's the expected formatting for manual pages;
+if you're formatting arbitrary text documents, using this option is
+recommended.
+
+=item B<-s>, B<--sentence>
+
+Assume each sentence ends in 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<-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.
+
+=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 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.
+
+=back
+
+=head1 DIAGNOSTICS
+
+If B<pod2text> fails with POD errors, see L<Pod::Text> and
+L<Pod::Parser> for information about what those errors might mean.
