TODO List
=========
o  Modify next unread to go into the next unread newsgroup too.
o  Get rid of tcp package which is out-dated and probably broken
   under Tk3.3.  Create own connect procedure to take its place.
o  Clean up news.c module, as there is a lot of unecessary code
   in it.
o  Clean up newsrc code so that we know if we need to reload it before 
   saving (right now if tknews is running and rescanning while you are
   reading news at home with rn, the newsrc changes you make with rn will
   be erased on the next tknews rescan)
o  Upgrade tknews to use tk3.3 and tcl7.0
o  Make Tknews self-contained :
        o  Compile binaries for sun4, hpux, and solaris.
        o  Update README to include info about what version of Tcl/Tk is
           used and explain the reason for the include directory.
o  Add incremental loading.
o  Add command to enter newsgroup without loading in first article.
o  Allow user to rearrange the order of the newsgroups in the listbox.
o  Allow user to mark a subject as read.
o  Examine and rearrange management of newsrc and active list.
o  Upgrade the tcl news data server.
o  Handle errors more intelligently.
o  Clean up preferences.
o  Write user's guide.
o  Improve on-line help documentation.
o  Add forward command to forward an article to a user.
o  Add threading
