# A simple cross-platform inetd style server for http://aminet.net/package/comm/tcp/netclip
#
# To use it add this line to your services file:
# netclip	2971/tcp
#
# And something like the following line to your inetd configuration file (args part in below example is for linux):
# netclip		stream	tcp	nowait	youruser	/path/to/netclipd.py	netclipd.py "xsel -i --display :0.0"
