24: .I Movie
25: converts a `movie script'
26: into an internal representation, then displays it in a window on a
27: Teletype 5620, AT&T630, or X-11 system (depending on which version has been compiled).
28: If the filename is of the form
29: .IB file .s ,
30: .I movie
31: creates the intermediate form in
32: .IB file .i ,
33: which will be used in subsequent calls if it is more recent than
34: .IB file .s ,
35: The options are:
36: .TP \w'\f5-t\ \fItermprog\ 'u
37: .BI -t " termprog
38: Load
39: .I termprog
40: instead of the default terminal program.
41: .br
42: .ns
43: .TP
44: .BI -m mem
