 # - "platforms" is empty if it exists on all platforms, otherwise it contains
 #   comma-separated list of the platform, just as they are if the symbol exists
 #   for those platforms, or prepended with a "!" if not.  This helps resolve
-#   symbol name replacements for platforms where the names are too long for the
+#   symbol name variants for platforms where the names are too long for the
 #   compiler or linker, or if the systems is case insensitive and there is a
-#   clash.  This script assumes those redefinitions are place in the file
-#   crypto/symhacks.h.
-#   The semantics for the platforms list is a bit complicated.  The rule of
-#   thumb is that the list is exclusive, but it seems to mean different things.
-#   So, if the list is all negatives (like "!VMS,!WIN16"), the symbol exists
-#   on all platforms except those listed.  If the list is all positives (like
-#   "VMS,WIN16"), the symbol exists only on those platforms and nowhere else.
-#   The combination of positives and negatives will act as if the positives
-#   weren't there.
+#   clash, or the symbol is implemented differently (see
+#   EXPORT_VAR_AS_FUNCTION).  This script assumes renaming of symbols is found
+#   in the file crypto/symhacks.h.
+#   The semantics for the platforms is that every item is checked against the
+#   enviroment.  For the negative items ("!FOO"), if any of them is false
+#   (i.e. "FOO" is true) in the enviroment, the corresponding symbol can't be
+#   used.  For the positive itms, if all of them are false in the environment,
+#   the corresponding symbol can't be used.  Any combination of positive and
+#   negative items are possible, and of course leave room for some redundancy.
 # - "kind" is "FUNCTION" or "VARIABLE".  The meaning of that is obvious.
 # - "algorithms" is a comma-separated list of algorithm names.  This helps
 #   exclude symbols that are part of an algorithm that some user wants to
 #   exclude.
