re:
    - 'make callcheck'     run the project's selftest with valgrind to
                           check for performance leaks
    - 'make check-verbose' run the project's selftest in verbose mode
    - 'make code'          generate code from models in src directory
                           (requires zproject and zproto)
    - 'make debug'         run the project's selftest under gdb
    - 'make memcheck'      run the project's selftest with valgrind to
                           check for memory leaks
    - 'make coverage'      generate project's selftest coverage report
                           expects --with-gcov option for configure
    - 'make clang-format-check'   check if project sources conform
                           to style requirements
    - 'make clang-format'         modify project sources to conform
                           to style requirements
    - 'make clang-format-diff'    modify as above and print 'git diff'
