# ABSTRACT: record interactive terminal sessions

=head1 SYNOPSIS

  ttyrec foo.ttyrec
  ttyrec -e 'nethack' nethack.ttyrec
  ttyrec -a

=head1 DESCRIPTION

This is an implementation of the C<ttyrec> program for recording terminal
sessions. All data that the program running in the terminal produces is
recorded, along with timing information, so that it can be replayed later (via
a ttyrec player such as the C<ttyplay> script distributed with
C<Term::TtyRec::Plus>).

This program is intended to be mostly a drop-in replacement for the C<ttyrec>
program distributed L<here|http://0xcc.net/ttyrec/index.html.en>.

=head1 OPTIONS

  ttyrec [-a] [-e <cmd>] [output_file]

=over 4

=item -a

Append to the ttyrec file, rather than overwriting it.

=item -e <cmd>

Execute <cmd>, rather than a shell. Defaults to C<$SHELL> or C</bin/sh>.

=item output_file

The file to write the ttyrec data to. This can be a named pipe. Defaults to
C<ttyrecord>.
