   all intermediate dirs;
 - various bug fixes.

--------------------------------------------------------------------------------

I am sorry for releasing 0.5 so full of bugs... There was a lot of...

 - fixed couple of awful bugs (memory corruption) resulting in core dumps etc;

   memory protection!)
 - you can set nonstandard port in nftp.ini

--------------------------------------------------------------------------------

Nearly the same as 0.52 but limited to 30 March 1996.

Planned for next version:
 - ability to use IP numbers
 - more error recovery

 - maybe remappable keys
 - ability to use arbitrary port
 - reget (restarting transfers)
 - uploading
 - something else I haven't realized yet
