1.0,12may89,rekn Written.
2.0,25may89,rekn Added support for named windows and selection by

This is a quick program that reads the header file defining cursors
and lets one change the cursor for a specified window. Window

\-r Selects the root window.

+ \-fg Selects the cursor's foreground color. The
+ default is black.

+ \-bg Selects the cursor's background color. The

! Not all windows will allow their cursor to be reset in this fashion
