  27 # This Makefile provides a framework for building the onbld python
  28 # modules with multiple versions of python.
  29 #
  30 # It expects as input:
  31 #
  32 #    PYSRCS   - List of python source files, these are also delivered as
  33 #               build product.
  34 #
  35 #    PYOBJS   - List of compiled python (.pyc) files, with no directory prefix
  36 #
  37 #    PYTOPDIR - Absolute (including $(ROOT)) path to which files will
  38 #               be installed, up until the version specific component.
  39 #
  40 #    PYMODDIR - Relative path to which files will be installed, below
  41 #               the version specific component.
  42 #
  43 #    For example, to install to /opt/onbld/lib/onbld/python*/bar/
  44 #
  45 #          PYTOPDIR = $(ROOTONBLDLIB)
  46 #          PYMODDIR = bar
  47 #
  48 #
  49 # It provides as output:
  50 #
  51 #    ROOTPYFILES - The list of $(ROOT)-relative paths to which python
  52 #                  source and binary files will be installed.  Your
  53 #                  Makefile's 'install' target should depend upon
  54 #                  this.
  55 #
  56 #    PYVERSOBJS  - The list of paths to compiled python build products,
  57 #                  including their subdirectory.
  58 #
  59 #    pyclobber   - A target on which 'clobber' should depend, which
  60 #                  removes the per-version python directories and the
  61 #                  output within them.
