# Slackware build script for gnsu

# Didier Spaier suggested (on the mailing list) that someone should
# package this, as a replacement for gksu. Sure, why not?

# I'm not a gksu user. If I were, I might not consider this a proper
# replacement. The main feature it's missing is, it doesn't grab the
# keyboard & mouse when prompting for a password (to prevent the user
# accidentally typing the password into some other window). Also, gksu
# will prompt for a command to run, if you don't supply one; gnsu just
# prints the --help message (on stderr, not in a dialog) and exits.

# OTOH, this is written in python3 and is pretty self
# contained. There's no compiled code and no extra dependencies.

# I've added a .desktop and icon, so this can replace gksu's "root
# terminal" menu entry... not that that ever *worked* because
# gksu.desktop executes "gksu /usr/bin/terminal", and Slackware
# doesn't have any such binary. It's supposed to be xfce4-terminal,
# but nobody ever got around to updating the .desktop file when XFCE
# changed its terminal binary's name.

# SalixOS has a "gnsu-0.3.1" package. The only differences between
# upstream's 0.3 and salix's 0.3.1 are that salix added an Irish
# (Gaelic?) translation, and modified the Portuguese translations
# incorrectly (fixed the "a a", but got rid of the "Por favor"). This
# patch adds the Irish translation and fixes the Portuguese
# *correctly*.
