# 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 (NCurses Disk Usage)
$PRGNAM:
$PRGNAM: Ncdu is a disk usage analyzer with an ncurses interface. It is
$PRGNAM: designed to find space hogs on a remote server where you don’t have
$PRGNAM: an entire graphical setup available, but it is a useful tool even on
$PRGNAM: regular desktop systems. Ncdu aims to be fast, simple and easy to
$PRGNAM: use, and should be able to run in any minimal POSIX-like environment
$PRGNAM: with ncurses installed.
