+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.
 
+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
