 GPIO bit-bang is well suited to PICMicro ICSP but not exclusively.
+WARNING: The underlying kernel API this module uses may have been removed from your running kernel.
+=== Build ===
+This module is built out of kernel and depends on the header files and tools found locally or may be cross compiled.
+For cross compilation, an example Makefile named `cross-compile.mk' is provided which should work for Raspberry PI OS as explained [[:tools:raspbian#kernel|here]].
+If the linux source directory was cross compiled and then copied to the target system to build the module, `scripts.sh' is provided to rebuild certain kernel header scripts locally. This is needed because some scripts are actually binary files on the foreign architecture.
