pkg-get is the original "install packages over the network" program for Solaris, written by Philip Brown, inspired by Debian's "apt-get" program. It is used as the primary transport of sites such as sunfreeware.com, opencsw.org, and others.
It works very similar to apt-get:
pkg-get install softwarename
pkg-get upgrade softwarename
It also has some additional useful functionality.
