+bitmask-launcher.c
+------------------
+
+A small, portable launcher for bitmask bundles.
+
+Problem that solves
+-------------------
+PyInstaller bundles leave everything (libs, data and the main binary) in a
+single folder. In a case like ours, there are too many files cluttering this
+top-most folder.
+
+We wanted to have a cleaner folder, with an obviously clickable entrypoint, that
+calls the binary that hides in an inferior folder.
+
