"""Simple "Buddy Pounce" script for Skype using Clisk.
Silas S. Brown 2013, Public domain, no warranty.

(Note: Only Skype 7 and below supported the API that Clisk used.
Microsoft's support for Skype 7 ended in November 2018 and I have
no idea if it can even connect to the Skype network anymore.)

Must go in the same directory as clisk.  You can get
clisk from http://www.dlee.org/skype/clisk/ (correct as
of 2013).  You might want to set up a bash function, e.g.
if you put clisk and pounce.py into /usr/local/clisk251
then you can add the following to your bash profile:
pounce () (cd /usr/local/clisk251;python pounce.py "$*";)

This script should be run with 1 argument, the full
display name of the Skype contact you want to watch for
(case sensitive).  You probably have to put it in quotes.

The script will read all status changes from clisk, and
will generate no output until the name you gave is
mentioned.  At that point a dialogue is displayed and the
script will then exit.

If you want the watch to persist across reboots etc then
you could add it to a login script or whatever, but you'd
then need to manually remove it when no longer required.
Note also that this script does not currently check the
status of a contact on startup; it reports status CHANGES.
