# 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 (The Ion Shell. Compatible with Redox and Linux.)
$PRGNAM:
$PRGNAM: Ion is a modern system shell that features a simple, yet powerful,
$PRGNAM: syntax. It is written entirely in Rust, which greatly increases the
$PRGNAM: overall quality and security of the shell. It also offers a level of
$PRGNAM: performance that exceeds that of Dash, when taking advantage of Ion's
$PRGNAM: features. While it is developed alongside, and primarily for, RedoxOS,
$PRGNAM: it is a fully capable on other *nix platforms.
