+3.13 Script invocation
+----------------------
+
+ Make rules may invoke scripts to build the kernel. The rules shall
+ always provide the appropriate interpreter to execute the script. They
+ shall not rely on the execute bits being set, and shall not invoke the
+ script directly. For the convenience of manual script invocation, such
+ as invoking ./scripts/checkpatch.pl, it is recommended to set execute
+ bits on the scripts nonetheless.
+
+ Kbuild provides variables $(CONFIG_SHELL), $(AWK), $(PERL),
+ $(PYTHON) and $(PYTHON3) to refer to interpreters for the respective
+ scripts.
+
+ Example::
+
+ #Makefile
+ cmd_depmod = $(CONFIG_SHELL) $(srctree)/scripts/depmod.sh $(DEPMOD) \
+ $(KERNELRELEASE)
