def usage():

Options (which can be given in any of the forms shown):
-b  --build      build [default]
-c  --clean      clean
-f  --force      force
-t  --translate  translate
-r  --recurse    recurse
-v  --verbose    verbose
-D  --debug      debug
path defaults to .

If executed with no arguments (or with a build argument) it does a
build, i.e., it looks for all *.ui and *.qrc files and makes sure that
the corresponding ui_*.py and qrc_*.py files exist and are up-to-date.

If executed with clean, deletes all ui_*.py and qrc_*.py files that have
corresponding *.ui and *.qrc files, and all *.pyc and *.pyo files.

If executed with force, it does a clean followed by a build.

If building and the translate option is given, after building, it runs
pylupdate4 on all .py and .pyw files it encounters, and then runs lrelease
on all .ts files it encounters. It does not use a .pro file so the .ts
files must be created in the first place, e.g., using pylupdate4 on one
of the source files and using its -ts option.

WARNING: Do not give any hand-coded files names that match ui_*.py or
qrc_*.py since these will be deleted by mkpyqt.py clean!

NOTE: If any tool fails to run, e.g., pyuic4, then edit this program and
hard-code the path; the variables with the tool paths are near the top
of the file.
