Initial import of genpkgng, a utility which will convert a pkgsrc

binary package to a FreeBSD binary pkg.  pkgsrc binary packages keep
more metadata, and do Dewey matching on package version numbers, so
it's not possible to convert in the other direction.

The DESCR says:

	This is a small utility to generate a FreeBSD pkg binary package
	from a pkgsrc binary package. It is invoked simply, using a
	command like:

		genpkgng ssam-1.9nb1.tgz

	and it will convert the pkgsrc binary package to a pkg one:

		% ./genpkgng.sh perl-5.18.1nb2.tgz
		Converting perl-5.18.1nb2.tgz
		-rw-r--r--  1 agc  users  16597860 Apr 24 19:01 perl-5.18.1nb2.txz

+.Nd utility to configure RAID sets
+.Sh SYNOPSIS
+.Nm
+.Fl nv
+.Op Fl v
+.Ar binpkg ...
+.Sh DESCRIPTION
+The
+.Nm
+command converts from a binary package
+generated from the pkgsrc infratsructure to a binary
+package which can be installed using the
+.Fx
+pkg packaging tool.
+.Pp
+It generates
+.Dq +MANIFEST
+and
+.Dq +COMPACT_MANIFEST
+metadata files, and also preserves the
+.Dq build information
+and
+.Dq build versions
+pkgsrc metadata, placing entries in the file system.
+.Sh RETURN VALUES
+The
+.Nm
+utility will return 0 for success,
+and non-zero for failure.
+.Sh EXAMPLES
+.Bd -literal
+% cp /usr/pkgsrc/packages/All/nettle-2.7.1nb1.tgz .
