# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in. You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

libnet: libnet
libnet:
libnet: Libnet is a high-level API (toolkit) allowing the application
libnet: programmer to construct and inject network packets. It provides a
libnet: portable and simplified interface for low-level network packet
libnet: shaping, handling and injection. Libnet hides much of the tedium of
libnet: packet creation from the application programmer such as multiplexing,
libnet: buffer management, arcane packet header information, byte-ordering,
libnet: OS-dependent issues, and much more. Libnet features portable packet
libnet: creation nterfaces at the IP layer and link layer, as well as a host
libnet: of supplementary and complementary functionality.
