+Subject: [PATCH] Onefile: Preserve the original argv[0] in
+ __compiled__.onefile_argv0
+
+In commit 9b0406b2a ("Fix, need to make sure sys.argv[0] is absolute
+for best usability"), the original argv[0] as received by the onefile
+binary is thrown away, breaking applications needing this information.
+
+To support these cases, record the original argv[0] in the
+NUITKA_ONEFILE_ARGV0 environment variable, for exposure via
+__compiled__.onefile_argv0. The field is made None if the onefile mode
+is not in use, or if the binary is not launched via the onefile
+bootstrapper.
