       +
       +
       +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:
