/*    This program fixes a problem with binary executable files that  */
/* are rounded up to the nearest multiple of 128 bytes by the XMODEM  */
/* file transfer protocol. The AmigaDOS loader fails to recognize a   */
/* a file as executable if it has additional zero bytes at the end.   */
/*                                                                    */
/*    There are several ways of fixing this, most of which have been  */
/* done by some other public domain program. This is the only program */
/* I know of that fixes the file in place. The others all copy the    */
/* during the fix, which is SLOW!                                     */
/*                                                                    */
/*    Method 1: Allow the user to specify the correct length and copy */
/* that many bytes from one file to another for him. It works, but it */
/* requires that the correct file length be posted on each bulletin   */
/* board that the file is uploaded to. This can lead to problems with */
/* multiple versions of the same program.                             */
/*                                                                    */
/*    Method 2: Analyze the file and copy each load module table over */
/* to another file as it is parsed. Upon encountering an unparsable   */
/* piece, discard the piece and close the output file. This is truly  */
/* automatic, but it still takes time to copy the file. Also, if the  */
/* internal format is really NOT a loadable module, it can lead to    */
/* to infinite loops and huge, invalid symbol tables.                 */
/*                                                                    */
/*    Method 3: (Used by This Program)                                */
/* Skip to the End-of-File mark, and move backward until the END-HUNK */
/* module piece is found. This represents the true end-of-program. To */
/* get rid of the trailing bytes WITHOUT copying the file, append an  */
/* empty symbol-table HUNK of exactly the size required to eliminate  */
/* trailing bytes. Now the AmigaDOS will just skip over the empty     */
/* symbol table entries and load the program fine. Also, this is a    */
/* fast operation. At first, it appeared possible to just write empty */
/* END-HUNK pieces at the end, but there is a counter buried in the   */
/* object code that specifies the number of hunks expected, and some  */
/* programs would not load due to the excessive number of hunks. The  */
/* symbol table method is much better.                                */
/*                                                                    */
