    K-FTP is a shell-based GUI for ftp logins and maintaining the
.netrc file.  It is hereby placed in the public domain  with  the
hope that it will be useful, but with no guarantee as to its mer-
chantability or fitness  for  a  particular  purpose.   Read  the
script and customize it; otherwise, use it at your own risk.

    K-FTP  was  intended to provide a GUI to the ftp user for se-
lecting hosts in the .netrc file.  It uses a  separate  directory
for  each host being connected to, in order to keep the dowloaded
files in an orderly hierarchy.  It changes the current  directory
to  a subdirectory corresponding to the name of the selected host
(the subdirectory is created if it does not exist), and  connects
to that host.

    The menu commands are self-explanatory.  The names of the ftp
command, directories, and the two temporary files can  be  recon-
figured  by  changing the shell variables FTPCMD, FTPDIR, TMPFILE
and SEDFILE, respectively, defined in the script's  header.   The
``dialog'' command that was provided with Linux Slackware distri-
bution 1.0.2, ``sed'' and ``bash'' are required.   Archive  files
with  names  ending  in  *.tar.gz  and derivatives, *.zip, *.zoo,
*.arc and *.lha are recognized and their directories shown if the
corresponding unarchiving program has been installed.

    As  it  stands, the script has many shortcomings: it is slow;
problems exist related to the GUI interface  program  ``dialog'',
e.  g. you can quit this info box by pressing the ``Esc'' key in-
stead of the ``Enter'' key.

    For suggestions and questions, you can contact me via the  e-
mail  address given below.  You are free to modify the script and
redistribute it, but I will not be responsible for those modified
versions unless I am convinced that it is an improvement.  In any
case, I would appreciate a copy, if you think you improved it.

    Thanks to the  Linux  developers community for maintaining an
operating system  so  flexible,  sound, and  open  to  evolution.
Special  thanks  go  to the SMU SEAS administration for providing
me with Internet access, to my advisor for  supporting  my  Ph.D.
studies, and to my wife for funding our personal computer.
