# 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 ':'.

$PRGNAM: $PRGNAM ( Virtual KVM switch for Linux machines )
$PRGNAM:
$PRGNAM: rkvm is a tool for sharing keyboard and mouse across multiple Linux
$PRGNAM: and Windows machines. It is based on a client/server architecture,
$PRGNAM: where server is the machine controlling mouse and keyboard and relays
$PRGNAM: events (mouse move, key presses, ...) to clients.
$PRGNAM: Switching between different clients is done by a configurable keyboard
$PRGNAM: shortcut.
