+ Packaging works as follows:
+
+ * Files are looked up the usual way, allowing us to override the
+ distribution-supplied scripts with our own alternatives in the
+ local path.
+
+ * The merged package is written to the same directory as the
+ packaging script (not ``$PWD``).
+
+ There is some room for improvements: Instead of reading a file with
+ fixed content from disk, the merge script could be composed
+ on-the-fly from a list of files and then written to memory (not sure
+ though if we can access shm_open or memfd and the likes from Lua).
