The adduser man page (vaguely) describes the steps required to add a user to a
FreeBSD system. The following is my adduser script which is based upon others
work and is applicable to FreeBSD release. It can be modified for other
systems. Note that two shell scripts are used to simplify the process.

# This is a shell archive. Remove anything before this line, then unpack
