# There exists a real need in the embedded community for a 
# captive portal with authentication. Till now I've been hording 
# this sweet little creation to myself.
#
# NoCatSplash is a Open Public Network Gateway Daemon. It performs as a 
# [captive/open/active] portal. When run on a gateway/router on a 
# network, all web requests are redirected until the client clicks I
# Accept to an AUP. The gateway daemon then changes the firewall rules
# on the gateway to pass traffic for that client (based on IP address
# and MAC address).
#
# NoCatSplash is the successor to NoCatAuth, which was written in Perl. 
# NoCatSplash is written in multi-threaded ANSI C in order to be smaller
# and work better on embedded style devices.
#
# NoCatSplash-Auth is the successor to them all which is NoCatSplash 
# with the features found on NoCatAuth but written in ANSI C in order to
# be smaller and work better on embedded style devices.
