1//! The environment of the programs artifactize starts: the person's own, as their terminal
2//! or desktop session gave it to artifactize.
3//!
4//! Only an app started from an AppImage runs with more. The bundle's AppRun and its hooks
5//! put the bundle's directories first in path lists such as `PATH` and `LD_LIBRARY_PATH` and
6//! set variables of their own; the app needs them to load its bundled libraries, while a
7//! system program it starts would load those libraries instead of its own and fail.
8//! Everywhere else this is the process environment unchanged.
