Build System Map2

autogen.sh

  calls build/buildcheck.sh which checks autoconf and autoheader and copies libtool stuff
  sets up  libtool services
  checks for python
  calls gen-make.py build.conf
  produces configure

gen-make.py

main(fname, gentype, verfname=None,
     skip_depends=0, other_options=None):

     computes the header dependencies (not sure what this means)
     write the (above obtained?) sqlite headers
     offer debug output if --debug is defined

useage_exit & class Options:
     It also offers interactive useage service -- when is that used?

build.conf -- used by gen-make.py to generate build-outputs.mk

[options] section:
  define includes
  define private includes
  test scripts
  SWIG includes of perl, ruby
