I have downloaded VNC 3.3.7 for Unix, and I have unzipped and untarred
the files. But I can't understand the Unix installation instructions
within the readme files.  Could someone please send me some step by step
instructions on how to install VNC 3.3.7 on a unix workstation?  I'm
actually trying to install it on to an IRIX operating system version

Thank you,
