+# ENVIRONMENT VARIABLES
+
+All application or library-specific environment variables (e.g. TMPDIR)
+may always be set in the Unicorn CONFIG_FILE in addition to the spawning
+shell.  When transparently upgrading Unicorn, all environment variables
+set in the old master process are inherited by the new master process.
+Unicorn only uses (and will overwrite) the UNICORN_FD environment
+variable internally when doing transparent upgrades.
