This is a handy tool for generating terse netmasks in several commonformats.  If you've ever maintained a firewall with more than a few rulesin it, you might use netmask to clean up and generalize sloppy rules left bythe netadmin before you.  It will also convert netmasks from one formatto another for the day you change your firewall software.See the file INSTALL for building and installation instructions.Please send all bug reports by electronic mail to:    netmask-bug@trap.mtview.ca.usNetmask is free software.
