+.Sh BUGS
+The evaluation of
+.Ar expression
+in a test is very simple-minded. Currently, the only form that works is
+.Ql .if ${VAR} op something
+For instance, you should write tests as
+.Ql .if ${VAR} = "string"
+not the other way around, which doesn't work.
+.Pp
+For loops are expanded before tests, so a fragment such as:
+.Bd -literal
+\&.for TMACHINE in ${SHARED_ARCHS}
+\&.if ${TMACHINE} = ${MACHINE}
+     ...
+\&.endif
+\&.fi
+.Ed
+won't work, and should be rewritten the other way around.
