# 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 (A cross-platform, GPU-accelerated terminal emulator)
$PRGNAM:
$PRGNAM: Alacritty is a terminal emulator with a strong focus on simplicity
$PRGNAM: and performance. With such a strong focus on performance, included
$PRGNAM: features are carefully considered and you can always expect Alacritty
$PRGNAM: to be blazingly fast. By making sane choices for defaults, Alacritty
$PRGNAM: requires no additional setup. However, it does allow configuration of
$PRGNAM: many aspects of the terminal.
