makefiles/

config.mk
makefiles/lint
--------------
  o Support more lint targets

makefiles/virtualenv.mk

makefiles/commands/kail.mk

  o mkdir -p for interactive use when WORKSPACE= is set.

Makefile
--------
  o Inline comment delimiters and help targets to improve readabilty.
  o Call macro banner-enter/banner-leave to hilight target output.
  o Change targets clean and help into double-colon rules so they
    are included when library targets are processed.
  o Update include $(MAKEDIR) imports, library makefiles are able to infer paths
    and define MAKDIR=, ONF_MAKEDIR=.
  o Define helper macro run-robot-test= allowing copy & paste robot command
    line to be refactored and reduced.
  o Define local target 'venv-install' allowing installation of the virtualenv
    followed by patching so a newer interpreter can be used locally for testing.
  o Shell command separator: replace ';' with '&&' to improve error detection.
  o target=gendocs: Split run-on command line into independent steps, activate
    script only applies to the for loop invoking tests.
