ncpfs-0.3 -> ncpfs-0.4
- removed bug causing kernel to crash on filenames too long
This was a typical C bug! Thanks to Uwe Bonnes,
bon@elektron.ikp.physik.th-darmstadt.de for his patience with this one.
ncpfs-0.2 -> ncpfs-0.3
- removed bug in get_pname_static
- removed bug in 'ncpmount -n'
- fake '.' and '..'
- return 0 for df and directory timestamps. See file BUGS
ncpfs-0.1 -> ncpfs-0.2
- should be compileable with gcc other than 2.7.0
- first attempt at read/write access
- more complete ncpmount.c
- included file ipx.tar

This is version 0.5 of ncpfs, a free NetWare client for Linux. For me
it works with 1.3.39, although this version has severe problems with
the socket layer. Your connection will block after you have sent 64k
of requests to the server. Alan Cox told me he would like to have that
fixed in 1.3.42 or so.

For the curious: the file ncplib_user.[ch] is a library that makes it
possible to send NCP requests to the server over a mounted
