   // Helper for custom perform(clean) implementations that cleans extra files

-  // which case it is ignored. Otherwise, the first character can be '+', in
-  // which case the extension is added (without the plus) to the existing
-  // extension (if any). In all other cases, the old extension is replaced
-  // with the new one. For example:
-  //
-  // clean_extra (a, t, {"+.d", ".lib"});

+  // rather than a file.  The next character can be '+', in which case the
+  // extension is added (without the plus) to the existing extension (if

+  // (so if you want to strip the extension, specify ""). For example:
+  //
+  // clean_extra (a, t, {"+.d", "/+.dlls", ".dll"});

+  // the prerequisites in the reverse order.
