By default, the typescript to display is assumed to be named ``typescript'',
but other filenames may be specified, as the second parameter.
If the third parameter is specified, it is used as a speed-up multiplier. For
example, a speed-up of 2 makes
go twice as fast and a speed-up of 0.1 makes it go ten times slower
than the original session.
% script -t 2> timingfile
Script started, file is typescript
