+nano 0.9.99-pre1 - 01/17/2001
+General
+	- Changed #ifdefs to check for both DISABLE_TABCOMP and
+	  NANO_SMALL, makes tiny option leave out tab completion, which
+	  should be left out in that circumstance.  Saves at least 5k.
+	- Previous change to #ifdefs DISABLE_TABCOMP and NANO_SMALL rolled
+	  back. (Rocco)
+	- Various #ifdef & #ifndef cleanups. (Rocco)
+	- Added message for when keypad goes awry.  Added code in main and
+	  function print_numlock_warning() to notify user, and added an
+	  apropriate section in the faq to refer to this brokenness.
+	- Added macros in nano.h for magic values that might be unclear in
+	  nano.c:global_init(). (Rocco)
+- configure.in:
+	- Fix for _use_keypad check breaking slang support (Christian
+	  Weisgerber).
+	- Changed to automatically define the 5 DISABLE varibles when
+	  NANO_SMALL (enable-tiny) is requested at configure.
+- faq.html:
+	- Added some info on making the binary smaller with the configure
+	  script.
+	- Added section on keypad bugginess.
+- files.c:
+  real_dir_from_tilde()
+	- Oops, fix case where buf ="~", silly crash (bug discovered by
+	  Neil Parks).
+  do_browser()
+	- Added space and - keys to do page up and down.
+  cwd_tab_completion(), input_tab()
+	- Changed bare malloc/calloc calls to nmalloc (found by Rocco).
+	- Added memset() to matchBuf to ensure sanity (Rocco, Adam).
+- nano.c:
+  ABCD()
+	- New function, figures out what kbinput to return given
+	  input common to several switch statements, allows us to 
+	  support the default Konsole key settings.
+  main()
+	- Alternate speller option no longer valid if DISABLE_SPELLER is
+	  active. (Rocco)
+	- Removed direct calls to usage() (#else) for -k (cut) or -s (speller)
+	  options when these have been disabled. (Rocco)
+	- Initialized kbinput to get around stupid compiler warning.
+  nano_small_msg()
+	- This function has been removed.  All references now call
+	  nano_disabled_msg. (Rocco)
+  version()
+	- When NANO_SMALL (enable-tiny) is defined, the 5 main DISABLE
+	  variables (SPELLER, HELP, JUSTIFY, BROWSER, TABCOMP) are not
+	  reported as enabled when Nano is called with -V (--version)
+	  command-line option. (Rocco)
+  usage()
+	- Alternate speller option no longer valid if DISABLE_SPELLER is
+	  active. (Rocco)
+  window_init(), handle_sigwinch()
+	- Added check for not having enough LINES to do anything useful,
+	  if so die with an error. (Rocco)
+  die_too_small()
+	- Function to print the window too small error message, avoids
+	  repeated string defs and globals.
+  do_justify()
+	- Small fix for totsize calculation (Rob)
+
+- fi.po:
+	- Update by Pauli Virtanen.
+
+nano 0.9.25 - 01/07/2001
+General - 
+	- New file browser code.  New functions in files.c:do_browser(),
+	  helper functions browser_init(), tail(), striponedir(),
+	  filestat().  New shortcut list browser_list.  Some new
+	  strings to translate.  Added function do_browse_from().
+	- Keypad code has been changed slightly.  Now checks for
+	  _use_keypad flag in window to see whether or not to turn 
+	  the keypad() back off when finished (taken from aumix).  Moved
+	  to winio.c where it should probably be anyway.  New confgure
+	  check for _use_keypad in window sstruct.  This will have to do
+	  for now.
+	- Moved keypad() calls for PDCURSES from main() to window_init()
+	  so the keypad continues to work after a Meta-X, for example.
+	  Fixed bug #51.
+- faq.html:
+	- Fix typos and small mistakes (Jordi).
+- files.c:
+  username_tab_completion()
+	- Added the (char *) sizeof when allocating memory for the filename
+	  array (Rocco).
+  cwd_tab_completion()
+	- removed skipping . and .. when tabulating matches.
+	- Added the (char *) sizeof when allocating memory for the filename
+	  array (Rocco).
+  do_writeout()
+	- Now takes an argument so the string typed in can be retained
+	  when calling the browser.
+  do_browser()
+	- Don't decrement longest by the length of path.  Fixes crashes
+	  on entering various dirs  (Rocco).
+	- Don't ungetch() the exit key, unneeded, fixes inerting a file
+	  causes exit code.
+- move.c:
+  page_down()
+	- Don't do an edit_update when there is only one page of text
+	  (fileage == edittop && filebot == editbot).  Fixes Bug #50.
+- nano.c:
+  main()
+	- Reorder the getopt options to be more or less alphabetical
+	  (suggested by Sven Guckes).
+- winio.c:
+  do_cursorpos()
+	- Optimizations and cleanups by Rocco Corsi.
+  do_credits()
+	- Spell Erik Andersen's name right.
+  titlebar()
+	- Now takes an arg, needed for browser function.
+  do_help()
+	- Changed way of temporarily bringing up shortcuts at the
+	  bottom in the help screen (actually works).
+- utils.c:
+  mallocstrcpy()
+	- Takes char pointers now instead of void (makes debugging a

-	The nano editor (Nano's ANOther editor) by Chris Allegretta
+	nano - a GPLed, enhanced clone of the Pico text editor.
                                       
-Manifesto
+Overview
+
+     The nano project was started because of a few "problems" with the
+     wonderfully easy-to-use and friendly Pico text editor.
+
+     First and foremost is its license: the Pine suite does not use the
+     GPL or a GPL-friendly license, and has unclear restrictions on 
+     redistribution.  Because of this, Pine and Pico are not included with
+     many GNU/Linux distributions.  Also, other features (like goto line
+     number or search and replace) were unavailable until recently or
+     require a command-line flag.  Yuck.
 
-     Nano is the editor formerly known as TIP (TIP Isn't Pico).
-     The nano project was started because of three main problems with the
-     wonderfully easy-to-use and friendly Pico text editor:
-     
-     - It's license is not the GNU GPL, and hence some Linux
-     distributions, including Debian (my favorite) don't always
-     include it/don't include binaries.  This is not necessarily a
-     problem, but an issue nonetheless.
-     
-     - Until recently, it had no ability to go to a line # from within
-     the editor. There was the +number command line option, but who wants
-     to exit a file to go to a specific line number? When I want to go to
-     a line, since I have to exit anyway, I just call up vi temporarily.
-     
-     - No search and replace feature. Well, apparently there is a flag
-     that lets you do a search and replace (-b in newer versions) but,
-     well, I still dont like it.
-     
      nano aims to solve these problems by emulating the functionality of
      Pico as closely as possible while adressing the problems above and
      perhaps providing other extra functionality.
