# VERSION  : 0.1 / 09 mai 2006
#this is a basic client/server popup messenger 
#which is launched by python tkpopup -c in client mode(to send a popup message)
#or python tkpopup.py -s to wait for incoming  
#please note you end your message with a double dot
#and you shutdown the server by sending him the string $$$ locally (which u can achieve via tkpopup.py client or by netcat or telnet or whatever....:)
#stupid "bug" to fix : if u send a line with .. and with other stuff,ur message is ended(yeah that s really stupid , i ll fix that later....

#ask user for default port and interface....
#the port on which we ll be listening on the other side 
#adjust to the settings u need (on unix platforms) 
#default_listening_port=8083
#default_interface="192.168.3.2"
#default_sending_port=8083
