### SCons build recipe for the GPSD project

# Important targets:
#
# build     - build the software (default)
# dist      - make distribution tarball
# install   - install programs, libraties, and manual pages
# uninstall - undo an install
#
# check     - run regression and unit tests.
# splint    - run the splint static tester on the code
# cppcheck  - run the cppcheck static tester on the code
# xmllint   - run xmllint on the documentation
# testbuild - test-build the code from a tarball

# Unfinished items:
# * Qt binding (needs to build .pc, .prl files)
# * Allow building for multiple python versions)
# * Out-of-directory builds: see http://www.scons.org/wiki/UsingBuildDir
#
# Setting the DESTDIR environment variable will prefix the install destinations
# without changing the --prefix prefix.

# Release identification begins here
gpsd_version = "3.0~dev"
libgps_major = 20
libgps_minor = 0
libgps_age   = 0
# Release identification ends here
