TODO
----

  - Standin files for libraries in combine module mean that multi
    level combines don't work properly as top level combine does not
    realise that lowest level directories have been changed.

  - Addition of support to allow template closure in a source directory
    when using cfront style repositories.

  - Include ObjectStore schema files in dependency generation. Really
    only want to do this for local schema file. Only needed for ObjectStore
    version prior to version 4.0.

  - Allow template closure to be done when only building shared libraries.

  - Allow use of Sun C++ 4.0 compilers in -ptt mode. Ie., attempt to
    delay template instantiation until program code file is being
    compiled.

  - It isn't possible to install generated header files unless they are
    being installed into subdirectory in install area with same name as
    makeit subdirectory.

  - Implement QUALIFIED_VARIANTS or equivalent.

  - QUALIFIED_??? will not work properly from a workspace.
