+# Example usage: %if %{defined with_foo} && %{undefined with_bar} ...

+# 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:
+#
+# %bcond_with extra_fonts
+# %bcond_without static
+# %ifdef with_extra_fonts
+# ...
+# %endif
+# %ifdef 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.
