# Boost.Python build and test Jamfile
#
# To run all tests quietly: jam test
# To run all tests with verbose output: jam -sPYTHON_TEST_ARGS=-v test
#
# Declares the following targets:
#   1. libboost_python, a static link library to be linked with all
#      Boost.Python modules
#
#   2. pairs of test targets of the form <name>.test and <name>.run
#      <name>.test runs the test when it is out-of-date, and the "test"
#      pseudotarget depends on it. <name>.run runs
#      a test unconditionally, and can be used to force a test to run.. Each
#      test target builds one or more Boost.Python modules and runs a Python
#      script to test them. The test names are:
#
#      from ../test
#
#         comprehensive         - a comprehensive test of Boost.Python features
#
#      from ../example:
#         abstract              -
#         getting_started1      -
#         getting_started2      -
#         simple_vector         -
#         do_it_yourself_convts -

# subproject-specific environment/command-line variables:
#
# PYTHON                - How to invoke the Python interpreter. Defaults to "python"
#
# PYTHON_ROOT           - Windows only: where Python is installed. Defaults to "c:/tools/python"
#
# PYTHON_VERSION        - Version of Python. Defaults to "2.1" on Windows, "1.5" on Unix
#
# PYTHON_TEST_ARGS      - specifies arguments to be passed to test scripts on
#                         the command line. "-v" can be useful if you want to
#                         see the output of successful tests.
#
# PYTHON_VECT_ITERATIONS - specifies the number of test iterations to use for
#                          the dvect and ivect tests above.
