NAME

IO::Pager::Page - use IO::Pager to emulate IO::Page, pipe STDOUT to a pager if STDOUT is a TTY

SYNOPSIS

Pipes STDOUT to a pager if STDOUT is a TTY

DESCRIPTION

IO::Pager is designed to programmaticly decide whether or not to point the STDOUT file handle into a pipe to program specified in $ENV{PAGER} or one of a standard list of pagers.

USAGE

   BEGIN{
     use IO::Pager::Page;
     #use I::P::P first, just in case another module sends output to STDOUT
   }
   print<<HEREDOC;
   ...
   A bunch of text later
   HEREDOC

If you wish to forgo the potential for a Broken Pipe foible resulting from the user exiting the pager prematurely load IO::Pager::Page like so:

   use IO::Pager::Page hush=>1;
