This is Shal's development area for MSFIO -- a library package for I/O to MS-DOS
diskettes.  It is currently being developed for the PDP-11 under RT-11 using the
DECUS-C compiler, but it should be easily portable to other environments.

The goal is to create utilities in support of "Sneaker-NET" between the host
system and MS-DOS systems.  For large files, or large collections of small
files, Sneaker-NET is likely to be faster than Kermit, and does not tie up an
MS-DOS system in the process.

Things to do
------------
Implement a better scheme for writing out the updated FAT and Directory. It
might be better to keep bit-maps of FAT and Directory sectors in the MSDEV
struct. Individual sectors can be marked "dirty" by fwrite() and can be flushed
by fclose().

Implement faster read & write routines: read/write more than one block at a
time, avoid the extra buffering implicit in the C runtime.

Get rid of MyFseek() and MyFopen(); work the necessary changes into the DECUS
library sources.

Handle RT-11 disks gracefully. It shouldn't be to hard for msfopen() to detect
the error return from devopen() and mark the MSFILE as belonging to an RT-11
file system instead of MS-DOS if that was the problem. Thereafter my I/O
routines could simply pass access to that file directly to the normal library
routines. This would make a general-purpose copy program very easy: it wouldn't
have to know which file system corresponded to its source and destination.
