-====== FRM Files ======
-  * Constant size = 1990 bytes (RBSIZ_FILE)
-  * Offsets are 1-based, not 0-based
-  * Little-endian format
-  * Rather good description at http://www.clicketyclick.dk/databases/xbase/format/frm.html up to the "data structures" part
-  * Other info from the source of the public domain DBE package at http://www.the-oasis.net/ftpmaster.php3?content=ftputils.htm
