#!/usr/bin/env python
# Generate set of projects mk files.
# Usage: python generate_mk.py PROJECTS_MK_DIR THRUST_SOURCE_DIR
# The program scans through unit tests and examples in THRUST_SOURCE_DIR
# and generates project mk for each of the tests and examples in PROJECTS_MK_DIR
# A single example or unit test source file generates its own executable
# This program is called by a top level Makefile, but can also be used stand-alone for debugging
# This program also generates testing.mk, examples.mk and dependencies.mk
