+# Based on those and a default (used when neither is given), bcond macros

-# Handle conditional builds. %bcond_with is for case when feature is
-# default off and needs to be activated with --with ... command line
-# switch. %bcond_without is for the dual case.
-#
-# %bcond_with foo defines symbol with_foo if --with foo was specified on
-# command line.
-# %bcond_without foo defines symbol with_foo if --without foo was *not*
-# specified on command line.
-#
-# For example (spec file):
-#
-# (at the beginning)
-# %bcond_with extra_fonts
-# %bcond_without static
-# (and later)
-# %if %{with extra_fonts}
-# ...
-# %else
-# ...
-# %endif
-# %if ! %{with static}
-# ...
-# %endif
-# %if %{with static}
-# ...
-# %endif
-# %{?with_static: ... }
-# %{!?with_static: ... }
-# %{?with_extra_fonts: ... }
-# %{!?with_extra_fonts: ... }
-
-#
-# The bottom line: never use without_foo, _with_foo nor _without_foo, only
-# with_foo. This way changing default set of bconds for given spec is just
-# a matter of changing single line in it and syntax is more readable.
