+
+For each binary-only library file from ESP-NONOS-SDK, this script searches for
+the exact commits and reports matching versions and commit urls.
+
+The argument must be the ESP-NONOS-SDK git-cloned directory.  It is left
+unmodified, and is locally cloned to work with.  The local copy is then
+removed.
+
+Because of libmain.a local tweaks, comparison is done for each .a file by
+extracting object files, removing the potentially modified ones
+(mem_manager.o time.o user_interface.o eagle_lwip_if.o) and doing a md5
+check against the core files.
