/* Program to send a string to an X-Window as if it was keypresses
* This is used by the xdvi help viewer to flip pages.
* First, very rudimentary version that does only recognize a few keys.
* The neat XWindows event code is due to Shane Smit (ssmit@caldera.com),
* the atrocious wraper loop running over a string is by A.Hulpke (who
* still cannot code proper C...) 27-Nov-00 */
