+Subject: [PATCH 2/3] plugin invocation: use python script as entrypoint
+
+Ink/Stitch is invoked by calling a script with command line parameters.
+Depending on the distribution format, this is bundled into a standalone
+binary -- at least for vanilla Ink/Stitch. For the nix version, we
+follow manual install, which does *not* bundle the file. Hence, the
+generation is patched to treat this packaged install as manual install,
+and to still refer to the python file.
+
+To keep the patchset small, only an if statement is changed, with the
+intent of only using the else path.
