- * These executables are made available with the +big feature, because they
- * are supposed to have enough RAM: Win32 (console & GUI), dos32, OS/2 and VMS.
+ * For Unix, Mac and Win32 use +huge by default.  These days CPUs are fast and
+ * Memory is cheap.
+ * Use +big for older systems: Other MS-Windows, dos32, OS/2 and VMS.
  * The dos16 version has very little RAM available, use +small.
+ * Otherwise use +normal
