# This script sets up a clean environment for a script or executable to execute in/under. It creates
|
|
# (and sets) $TMPDIR initialized to a clean & unique temporary directory, creates a new $HOME, sets
|
|
# the relevant XDG_* directories to point to subdirectories of that $HOME, cleans up any potentially
|
|
# problematic environment variables, executes the provided command, waits for it to exit, then
|
|
# cleans up the newly created environment before bubbling up the exit code. $PWD is not changed.

# If sourced instead of executed, sets up the environment as before but does not execute any payload
