 This git repo contains the following scripts that make interfacing with git.c.o, reimzul and nazar as easy as possible.
 
+Tools:
+ * get_sources.sh: when run from inside a package git checkout, will download the relevant non-text sources from the lookaside cache and drop them into the SOURCES/ dir; note: it will generate 0 byte files in place, rather than download them.
