Bug#1104462: (fwd) Bug#1104462: ttfdump undocumentedly clobbers file specified by argv[2]
Hi Karl, hi all,
bug report in Debian, but that might be a good idea to warn if excessive
arguments are given, or the dump output (second file argument) is
already present.
Also, the man page does not list that
ttfdump -o OUTPUT TTF
is the same as
ttfdump TTF OUTPUT
It is a bit confusing I admit.
Best regards
Norbert
