Cool. Isn't it a better idea to improve this script to auto-order the
header files and land it under src/tools/pginclude/headerssort? It can
then be reusable and be another code beautification weapon one can use
before the code release.

FWIW, I'm getting the syntax error when ran the above shell script:

headerssort.sh: 10: Syntax error: "(" unexpected
