+I have edited this code to work on modern compilers.
+
+Russ Cox
+
+---
+
+There are times during debugging when it would be real useful to be able to
+print the fields of an event in a human readable form.  Too many times I found 
+myself scrounging around in section 8 of the Xlib manual looking for the valid 
+fields for the events I wanted to see, then adding printf's to display the 
+numeric values of the fields, and then scanning through X.h trying to decode
+the cryptic detail and state fields.  After playing with xev, I decided to
+write a couple of standard functions that I could keep in a library and call
+on whenever I needed a little debugging verbosity.  The first function,
+GetType(), is useful for returning the string representation of the type of
+an event.  The second function, ShowEvent(), is used to display all the fields
+of an event in a readable format.  The functions are not complicated, in fact,
+they are mind-numbingly boring - but that's just the point nobody wants to
+spend the time writing functions like this, they just want to have them when
+they need them.
+
+A simple, sample program is included which does little else but to demonstrate
+the use of these two functions.  These functions have saved me many an hour 
+during debugging and I hope you find some benefit to these.  If you have any
+comments, suggestions, improvements, or if you find any blithering errors you 
+can get it touch with me at the following location:
