Ncat's parser is a reimplementation of the parser in Nmap's
TargetGroup.cc. Believe me, I felt bad about that. I decided that
reimplementing it was the right thing for a few reasons. First, Ncat is
a pure C program with no dependencies on any (C++) Nmap files. Linking
with TargetGroup.o would change that. Second, I wanted support for IPv6
netmasks. Third, I had a neat idea for representing IPv4 ranges as bit
vectors.

It could always be moved to nbase and shared between nmap and ncat if
that turned out to be desirable.  Though, as you note, perhaps the
uses are different enough that it isn't worthwhile.

Cheers,
