Changes against qprompt version 2 (of Alex Kent)
---------------------------------

I have changed the command line interface and added a lot of new
options. Here are the changes, that make qprompt 2.1 incompatible 
with the earlier version:
- made exit codes more intuitive;
  now arg1 exits with 1, arg2 with 2 and so on,
  special cases (timeout, RETURN key) now exit with values >=100
- timeout is now treated as an option and must be preceded 
  with a dash
- characters in one arg must no longer be separated by a '/'

Here are the new features of qprompt 2.1:
- disable timeout after first key-press by default
- allow to change the above behavior of the timeout after the 
  first key-press to
  - restart timer after a key-press
  - don't care about key-presses (the old behavior)
- added option to disable special RETURN key processing
- optionally display a default or user specified prompt
- read key input from stdin by default 
  (was from /dev/tty before which made use difficult in /etc/rc etc.)
- allow reading input from any specified device
  (i.e. /dev/tty to allow the old behavior)
- optionally write exit code to stdout
  (useful for testing or pipes)
- extended usage info
- added version and date to the manual page
- updated the manual page to reflect the new options 
- included a Bourne Shell example in the man page
- added simple makefile
See the manual page for more details.
