The first command creates a regular expression for matching all bitcoin-config.h symbols in the following form: ^(?!//).*(AC_APPLE_UNIVERSAL_BUILD|BOOST_PROCESS_USE_STD_FS|...|_LARGE_FILES). It was generated with:
./autogen.sh && printf '^(?!//).*(%s)' $(awk '/^#undef/ {print $2}' src/config/bitcoin-config.h.in | paste -sd "|" -)

The second command holds a list of files and directories that should not be processed. These include subtree directories as well as some crypto files that already get their symbols through the makefile.

The third command checks for missing bitcoin-config headers in .cpp files and adds the header if it is missing.

The fourth command checks for missing bitcoin-config headers in .h files and adds the header if it is missing.

The fifth command checks for unneeded bitcoin-config headers in sources files and removes the header if it is unneeded.
