#h This is the networking libraries update routines stripped out of setup_ssh.
#h There are now newer & better versions of ssh available than what setup_ssh
#h installs, but the code that updates the libraries is still very useful.
#h 
#h The main purpose of this is to get updated versions of certain core
#h shared libraries installed in a safe manner so that 5.0.4, non-updated 5.0.5
#h & 5.0.6 systems can run programs that were compiled on updated 5.0.5, 5.0.6
#h or newer systems.
#h 
#h Automatically takes the appropriate actions (including no action) depending
#h on which version of OpenServer you have and depending on which if any
#h updates you may have already applied.
