# The waf build system has slightly different semantics for configuration options from the GNU autotools,
# because the option flags are available at configuration (like autotools), but also at build time (i.e.
# like the "make" step in "./configure; make; make install"), and they don't have to have the same values.
# This is handled here by recording the option values at the config step, and using them as defaults in the
# build step. The convention used for the recorded value is:
# -1 for option disabled,
# 0 for option not specified (i.e. choose a default),
# +1 for option enabled.
#
# Build all variants

#
# Since multiple variants are possible, the exclusive pairs for a single variant have more possibilities.
# For examle, when building only one variant there are two (exclusive) possibilities for National Language Support,
# the built target must have NLS enabled or disabled. However when building multipble variants there are three
# possibilities, (1) build only variants with NLS enabled, or (2) build only variants with NSL disabled, or (3) build
# both kinds of variants. It doesn't make too much sense for the fourth combination (no enabled OR disabled NLS variants)
# because then there are no variants at all being built.
#
# Rather than trying to come up with wording for the option names that makes the 3 possibilities clear, I've kept the
# enable/disable terminology and added a negation style name with its own enable/disable options. To continue the NLS
# example from above, I've kept --enable-nls and --disable-nls, but added SLS (Single Language Support) with the options
# --enable-sls and --disable--sls.
