# ---

# module could use some naming help;
# main idea is running behind a launch program,
# one of `./prepare/launch.linux.sh`
# or     `./prepare/launch.nix.sh`

# prepare/proceed.sh seems sensible?
# only our purpose should be making sure is easily runnable.

# more and more, seems like this one program
# plays the role of both earlier `prepare/launch.*.sh` ones.

# probably makes more sense to scrap `./prepare`,
# has been a hodgepodge of old and decaying recipes.

if [ $(whoami) = "root" ]; then exit 1; fi

# should be runnable on nearly any machine.
