// Note: Byte-by-byte copying is slow.  If you were writing to a file, try:
//     long len = filelength(fileno(source_file));
//     char* buf = xmalloc(len);
//     fread (buf, 1, len, source_file)
//     fwrite (buf, 1, len, dest_file);
// That would eliminate repeated function calls and ultimatly be faster.
