-/* Included in this file are all system dependent routines.  Extensive use
- * of #ifdef's will be used to compile the appropriate code on each system:
- *
- *    UNIX:        all UNIX systems.
- *    UNIX_BSD4_2: UNIX BSD 4.2 and later, UTEK, (4.1 BSD too?)
- *    UNIX_SYSV:   UNIX system V
- *    UNIX_V7:     UNIX version 7
- *
- * All UNIX code should be included between the single "#ifdef UNIX" at the
- * top of this file, and the "#endif" at the bottom.
- *
- * To change a routine to include a new UNIX system, simply #ifdef the
- * existing routine, as in the following example:
- *
- *   To make a routine compatible with UNIX system 5, change the first
- *   function to the second:
- *
- *      md_function()
- *      {
- *         code;
- *      }
- *
- *      md_function()
- *      {
- *      #ifdef UNIX_SYSV
- *         sys5code;
- *      #else
- *         code;
- *      #endif
- *      }
- *
- * Appropriate variations of this are of course acceptable.
- * The use of "#elseif" is discouraged because of non-portability.
- * If the correct #define doesn't exist, "UNIX_SYSV" in this case, make it up
- * and insert it in the list at the top of the file.  Alter the CFLAGS
- * in you Makefile appropriately.
