Xmatrix name patch
A patch for Jamie Zawinski's Xmatrix screensaver (4.21) that allows a user to 
replace their name for Neo's. Jamie thinks this is a dumb idea, I don't see why since you can replace the phone number to be traced. Might as well go all the way.


name.patch


Apply as follows:

At the top level of the xscreensaver source tree do the following,

# patch -p0 < name.patch


larry@bokchoy:~$ patch -p0 <name.patch
patching file xscreensaver-4.21/hacks/xmatrix.c
larry@bokchoy:~$    


Under the xmatrix advanced settings when you execute xscreensaver-command -prefs 
add -name yourname to the command used to execute xmatrix.
