1 - Clean up the command-line parsing.
3 - Cleaned up documentation, with a real man page.
5 - Support for clusters larger than 16K. This would require changing
6 a lot of the SYSLINUX internals so we can read partial clusters;
7 change the current "cluster pointers" to become
8 "cluster:sector pointers". (32K may be doable.) Microsoft
9 documentation claims that 32K is the maximum legal value although
10 "some versions of some systems allow 64K".
16 - Support files that span multiple input media
18 - Clean up the handling of sections
20 - Add "localboot" support to SYSLINUX (using the ISOLINUX feature set.)
