gpsd/SConstruct

""" SCons build recipe for the GPSD project

Important targets:

build      - build the software (default)
dist       - make distribution tarballs .gz and .xz, plus .zip
zip        - make distribution zip
install    - install programs, libraries, and manual pages
uninstall  - undo an install

check      - run regression and unit tests.
audit      - run code-auditing tools
testbuild  - test-build the code from a tarball
website    - refresh the website
release    - ship a release

--clean    - clean all normal build targets
-c         - clean all normal build targets

Useful configuration options:
debug=yes     -- Compile and link with debugging options. Turns off
                 optimizations,
debug_opt=yes -- Compile and link with debugging options. Leaves on
                 optimizations,

Useful scons options:
--warn=all -- to see scons warnings

Setting the DESTDIR environment variable will prefix the install destinations
without changing the --prefix prefix.

Pretty much all this file does is create the variant_dir, and call SConscript.
