pkgwrite is a simple tool to make Debian and Redhat packages out of a single specification file.
pkgwrite is licensed under the GNU GPL and LGPL: this dual licensing is just a small convenience, though. You may use pkgwrite to package software which is under any license: however pkgwrite itself may only be included with GPL or LGPL software.
If this restriction prevents you from using pkgwrite for Free Software (which includes the BSD or MIT licenses) please don't hesitate to contact me.
