=head1 NAME

stream_ttyrec - play a ttyrec to a termcast channel

=head1 VERSION

version 0.13

=head1 SYNOPSIS

  stream_ttyrec [options] [ttyrec_file]

=head1 DESCRIPTION

This program will stream a ttyrec file to the given termcast channel. The
ttyrec file may be given on the command line, or it will be read from STDIN.
See L<App::Termcast> for options documentation.

This program also accepts some additional options:

=over 4

=item C<< --speed <n> >>

Set a multiplier for how fast the ttyrec should be played back (C<--speed 2>
means twice as fast).

=item C<< --clamp <n> >>

Set the maximum delay between any two frames in the ttyrec. If unset, there is
no maximum (the ttyrec will be streamed as written).

=item C<< --nowait >>

Disable all delays between frames (equivalent to C<--clamp 0>).

=item C<< --peek >>

"Peek" at a ttyrec that is currently being written. This will seek to the end
of the file and stream new ttyrec frames as they become available.
