Usage: $0 <term1> <term2>
Usage: $0 -c <term1> <term2>
Compares the entries in the termcap.src for <term1> and <term2> and
print the keys and definitions on the screen. This can be used to reduce
the size of two similar termcap entries with the "tc" option.
Usage: $0 -l [term]
Show all lengths or the ones for terminals matching [term]
Usage: $0 -p <term>
Print all information about <term>
Usage: $0 -r <term>
Print all relations from and to <term>
