# SCons build recipe for the GPSD project
# Important targets:
#
# build - build the software (default)
# dist - make distribution tarball
# 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
# sconsclean - clean up scons dotfiles (but not the database: .sconsign.dblite)
#
# Setting the DESTDIR environment variable will prefix the install destinations
# without changing the --prefix prefix.
# Unfinished items:
# * Out-of-directory builds: see http://www.scons.org/wiki/UsingBuildDir
# * Coveraging mode: gcc "-coverage" flag requires a hack
# for building the python bindings
# * Python 3 compatibility in this recipe
# Since SCons 3.0.0 forces print_function on us, it needs to be unconditional.
# This is recognized to be a bug in SCons, but we need to live with it for now,
# and we'll need this for eventual Python 3 compatibility, anyway.
# Python requires this to precede any non-comment code.
