   2 # Toplevel Makefile for the Modular C++ Build System
   3 #=========================================================================
   4 # Please read the documenation in 'mcppbs-doc.txt' for more details on
   5 # how the Modular C++ Build System works. For most projects, a developer
   6 # will not need to make any changes to this makefile. The key targets
   7 # are as follows:
   8 #
   9 #  - default   : build all libraries and programs
  10 #  - check     : build and run all unit tests
  11 #  - install   : install headers, project library, and some programs
  12 #  - clean     : remove all generated content (except autoconf files)
  13 #  - dist      : make a source tarball
  14 #  - distcheck : make a source tarball, untar it, check it, clean it
  15 #  - distclean : remove everything
  16 #
