+# We can't make commitment to supporting Microsoft assembler,
+# because it would mean supporting all masm versions. This in
+# in turn is because masm is not really an interchangeable option,
+# while users tend to have reasons to stick with specific Visual
+# Studio versions. It's usually lesser hassle to make it work
+# with latest assembler, but tweaking for older versions had
+# proven to be daunting task. This is experimental target, for
+# production builds stick with [up-to-date version of] nasm.
