Manpages and more!
ChangeLog
- Instead of giving a "You must run this as root." message and nothing else, you'll get that message and the version/help information.
- The filename was changed from 'hostfw.sh' to simply 'firewall'.
- There is a makefile to generate a new version of the manpage (requires pandoc).
- The makefile also installs (edit PREFIX and MANPREFIX to change destinations). Defaults to /sbin and /usr/share/man.
