Changes from 0.9.5 to 0.9.6
                   (Gustav Hllberg, Massimiliano Ghilardi) 16 Oct 1997
	* Fixed a nasty security hole in MPI messages
	* Fixed handling of \; at the end of a command
	* Fixed some other problems:
	  short messages from MUD could interfere with remote editing,
	  #bind escape sequences containing \0 were incorrectly printed/saved
	
Changes from 0.9.4 to 0.9.5
                   (Gustav Hllberg, Massimiliano Ghilardi) 18 Sep 1997
	* Continued code cleanup
	* Allowed aliases starting with `#'
	* Removed #speedwalk, #info, #echo, #keyecho, #compact and #debug
	  and turned them into #options: `#option echo' and so on.
	  For compatibility, `#echo' is aliased to `#option echo' and so on.
	* Fixed a dangerous bug making cursor jump to start of typed text
	  when receiving a line that wraps. The bug appeared in 0.9.4,
	  so blame Gustav ;)
	* Fixed an old bug making powwow sometimes miss a bind
        * Made the command from a bound key appear with `hilight' setting
        * Made a DEFAULT_HELP_DIR define in powwow.c
	* Changed to from ' ' to ` ' in some messages

Changes from 0.9.3 to 0.9.4 (Massimiliano Ghilardi) 04 Sep 1997
	* Included all the huge changes made by Gustav Hllberg:
	  I really have no time to double-check them all.
	  If something works in 0.9.2 but is broken in 0.9.4,
	  you know who to bother :)
	* Small esthetic changes in the source, no effects on executable
	* Changed identifier for regex #actions from ']' to '%'

Changes from 0.9.2 to 0.9.3 (Gustav Hllberg) 11 Aug 1997
	* Fixed so packets ending with \r*\n\r* set promptstr to ""
	* Made all signal handlers permanent (sig_permanent)
	* Debugged and reinstalled #option (it was commented out for some
	  obscure reason), allowing storage of command history and word 
	  completions in the savefile. Added the 'exit' option to allow
	  powwow to autoexit when the last connection closes
	* #echo, #info, #wrap and #debug now get saved in the savefile
	* Made repetitive use of &complete-word and &complete-line cycle 
	  through possible completions
	* Made a memory-safe strdup (called str_dup)
	* When starting a child viewer/editor, that process' TITLE 
	  environment variable is set to something appropriate (?)
	* Regular expressions (Extended POSIX) available for actions;
	  uses GNU rx
	* Actions with label "" forbidden
	* Added the #delim command to change word delimeter mode
	* Whenever main_conn changes permanently, linemode is set to 0 and
	  promptstr to ""
	* Fixed a crashy bug in the >: operator
	* Fixed the notorious extra-space-on-insert bug (both 'ic' and 'im'
	  shall NOT be sent if you want to insert something) and a VT100
	  mode bug while I was feeling creative
	* Made the local editing protocol respect prompts (i.e. they get
	  rewritten after protocol messages are shown). After texts are sent
	  back to the mud, the output buffer is flushed (no more pressing
	  ENTER after you've stopped editing!)
	* Fixed a few bugs in #mark; pattern "&" doesn't crash anymore.
	  Patterns with consecutive wildcards never worked, so I forbade them.
	  It could be implemented, but I hardly think it's worth it
	* Added the ANSIBUG compiler directive to fix the bug in some terms
	  that show new lines in the current output attrib (screws #mark e.g)
	* Made '#connect' without parameters try to open a connection
	  titled 'main' to 'hostname' (if specified) if no conns are open.
	  The initstr from #init will be used in this case
	* Added &transpose-words, &upcase-word and &downcase-word (defaults
	  to M-t, M-u and M-l). Repetition of the latter two changes case
	  of the whole line
	* Changed default key names to be more emacs-like (C-b, Ret etc)
	* Made #host get written to the savefile iff *hostname != 0, and 
	  if powwow is started as 'powwow filename', without any #host in
	  the file, #init is ran immediately
	* Fixed a bug in cmd_print() that didn't cope with $0 not being set
	* Allowed \0 to be part of a bound key's escape sequence. New format
	  for #bind allows octal \012 be part of the string representation
	  of the esc seq (chars with high bit set get saved in octal now)
	* Made permanent variables $last_line and $prompt
	* Made "#var" without arguments list all defined named variables

Changes from 0.9.1 to 0.9.2 (Massimiliano Ghilardi) 04 Jun 1997
	* Added #keyecho command toggle echo of binded keys.
	  Previously, this was controlled by the generic #echo command.
	* CTRL-C can now safely interrupt blocking commands like
	  #connect and #bind.
	* POWWOWDIR is now used correctly in all cases:
	  not only when starting powwow with a filename but also when using
	  #load, #save or #file
	* Changed #file syntax. Now you need = before the save-file.
	  Putting = alone undefines the save-file and disables autosave
	  when you quit.
	* Cleaned up naming conventions: 'session' means editing session
	  while 'connection' means remote host connection.
	* Fixed handling of 8 bit chars typed from keyboard
	* Fixed '#reset bind' which was not reloading cursor binds
	* Fixed remote host name spelling in files generated by #save.
	* Fixed a bug that caused powwow to crash when failing to
	  connect to a mud.

Changes from 0.9.0 to 0.9.1 (Massimiliano Ghilardi) 31 Apr 1997
	* New connections opened with #connect are set as main connection.
	  You will have to switch back manually if you need it.
	* Cleaned up multiple connection support. Better error handling.
	* Cleaned up TELNETBUG support. I did not use it recently,
	  and was out of sync.
	* Enhanced #bind syntax: now you can specify control codes
	  sent by your keyboard directly from the command line.
	  As a side effect, #exe <file now works also on files created
	  with #save
	* Added #rebind command. Changes the control codes associated
	  to a key binding without changing its name or its effect.
	* Added #quit command.

Changes from 0.8.6 to 0.9.0 (Massimiliano Ghilardi) 29 Apr 1997
        * Added FreeBSD support in make_it (thanks to Jaako Knuutila)
        * Cleaned up terminal interface.
	* #save and #load now accept a filename as argument
	* Handle SIGQUIT as SIGINT: use to stop long or infinite loops
	* Now can switch main connection on the fly with ##<connection-name>
	* Allow powwow #commands also on subsidiary connections

Changes from 0.8.5 to 0.8.6 (Paolo Gatti, Massimiliano Ghilardi) 28 Apr 1997
        * Finally and definitively changed the name to powwow.
	  Previously, sometimes the program was referred to as pow-wow
	  and sometimes as powwow, generating confusion.
        * Partial port of powwow to AmigaDOS. Incomplete, will NOT compile.
	  Paolo abandoned the project, so maybe it will just never compile.
	* Fixed a bug causing extra new-lines on screen when powwow received
	  strange data sequences like ASCII codes 10 13
	  (on DOS, new-line is 13 10, while on UN*X is 10 only)
        * Fixed a bug in #mark not matching correctly the wildcard $
        * Powwow crashed #loading files containing empty lines. Fixed

Changes from 0.8.4 to 0.8.5 (Massimiliano Ghilardi)
	* Fixed a bug introduced by updating files from cancan 2.6.0b sources
	  (happened in version 0.8.3): powwow was sendind TWO new-line chars
	  instead of one immediately after every password.

Changes from 0.8.3 to 0.8.4 (Massimiliano Ghilardi)
	* Fixed (I hope definitively) an ancient bug:
	  some lines were sometimes printed twice or not printed at all.
	  It is still the bug that appeared in version 0.4...
	  The bug was almost fixed in version 0.8b but reintroduced in 0.8.3

Changes from 0.8b to 0.8.3 (Massimiliano Ghilardi)
	* Slightly changed version numbering (0.8.3 instead of 0.8c)
	* #save and #load are now safe even in case of errors
	  (example: `disk full')
	* hitting a #bind-ed key now echoes the corresponding command
	  only if #echo is on
        * updated term.c (terminal handling code) and tel.c (telnet code)
	  with files from cancan 2.6.0b (yes, I shamelessly copied them)
	  No external changes anyway (unless I introduced some bugs)
          note: beam.c NOT updated/copied
        * 'follow' standalone mini-program added (see README.follow)
        * #key is now explicitly stated not to support editing keys.
	  They cannot be added cleanly without rewriting the line-editing code
	  from scratch ('#key up' and '#key return' give the biggest problems)
	  and I don't have the time for that right now
        * blink attribute added
        * Now can use multiple attributes in #mark, #hilite, #color
	  example: #mark *An Orc*=inverse bold blue on red
	  Note: bold, blink, underline and inverse must appear BEFORE colors
	* fixed some bugs:
	* changed "VERSION" to "POWWOW_VERSION" in powwow.c.
	  It seems some compilers use VERSION for internal purpouses...
	* #wrap mode was discarding lines containing only escape sequences
	  (example: color codes coming from the MUD)
        * #hilite was restoring hilight attributes after EVERY line
	  coming from the MUD
	* self-recursive aliases were causing crash after 100 loops instead
	  of trapping error and reporting '#error: stack overflow'
	  (not always, and not on all OS). Now they are completely safe.
	  Note: they still eat 1MB of memory (10K per loop - released
	  immediately after)

Changes from 0.8a to 0.8b (Massimiliano Ghilardi)
	* hexadecimal numbers added (and in any other base)
	  can be used only from calculator, prefix is #
	* '#write' command added
	* fixed a bug with #nice affecting #load
	  now #load places actions/marks in memory in the same order as
	  config file, indipendently from #nice value.
	  Also, default #nice changes from 1 (top) to 0 (bottom)
	* fixed a bug in #save that sometimes caused crashes and destroyed
	  config file
	* now word completion (issued with TAB key) checks
	  word completion list _before_ built-in commands

Changes from 0.8 to 0.8a (Massimiliano Ghilardi)
	* remind me NEVER to work on Sunday, because I filled version 0.8 with
	  these bugs (now fixed):
	  - some debugging stuff was not deleted from official version
	  - deleting a named variable could cause a crash
	  - creating a named variable was giving a message even while reading
	    a definition file
	  - #settimer was not working due to a change in version 0.8
	  - forgot to say that #map variable was added
	* #rand, #map and #timer variables renamed rand, map and timer
	  (removed the #) - sorry for the change but it was necessary.
	* removed limit of 50 named variables of each kind (numeric and string)
	  now the only limit is the memory available

Changes from 0.7b to 0.8 (Massimiliano Ghilardi)
	* #mark now accepts wildcards ($ for a single word, & for a string)
	* named variables are now supported
	* #assign renamed #var (I never liked the name 'assign' ...)
	  also, #var can be used to delete variables from memory
	* #nice command added. It sets/shows priority of new actions/marks

Changes from 0.7a to 0.7b (Finn Arne Gangstad)
        * make_it now also works for sunos 5.x, irix 5.x and hpux 9.x

Changes from 0.7 to 0.7a (Massimiliano Ghilardi)
	* fixed a _HUGE_ hole in security: $n in actions was matching also ;
	  (but not spaces) so robotic actions gave a chance to other players
	  to force you (*AAARGH*)
	* startup changed: now powwow does not clear screen when executed,
	  but jumps to the end of screen (this avoids mess in the first lines
	  you get from the mud)

Changes from 0.6d to 0.7 (Massimiliano Ghilardi)
	* finally fixed the unpleasant bug of auto-wrap making confusion when
	  receiving lines that contain escape sequences
	  (the fix in 0.6d was far from satisfactory)
	* high-intensity colours added (for the terminals that support them)
	* #assign can be used to put the contents of a variable on input line
	* number of global variables raised to 50, max lenght of string
	  variables raised to 512 bytes
	* #settimer command added, '#time' variable changed into '#timer'
	* fixed a bug: math operator >= was wrong, worked as <=

Changes from 0.6c to 0.6d (Massimiliano Ghilardi)
	* break key now is also used to stop command-parsing. Useful to stop
	  long or infinite loops without exiting from powwow.
	* #stop command added. It disables all active delayed commands.
	* #mark now works also with prompts (was not implemented before)
	* fixed an ancient bug with #action not working on lines splitted into
	  multiple data packets by telnet.
	* fixed two other ancient bugs:
	  #mark not working on auto-wrapped words
	  and auto-wrap making confusion when receiving lines that contain
	  escape sequences (only partially fixed to be honest)
	* Now the unescaping is performed ALSO on quoted strings, when powwow
	  evaluates them. Thus there might be to update your definition file
	  if it contains escapes placed in strings.

Changes from 0.6b to 0.6c (Massimiliano Ghilardi)
	* If you have problems with #rand, random() and srandom() (typically
	  your compiler is unable to find the functions) you can define
	  NORANDOM at compile time. (temporary solution)
	* Now also editing keys can be redefined
	* #assign command added (same syntax of #print, #send and #exe)
	* Now you can specify start and end line of a file or output of Bourne
	  shell command when using #print, #send, #exe, #emulate or #assign
	* #debug command added (try it in test mode...)
	* Now #echo, #info, #speedwalk and #debug also accept 'on' or 'off'

Changes from 0.6 to 0.6b (Massimiliano Ghilardi)
	* #emulate command added (same syntax of #print, #send and #exe)
	* now also prompts can be intercepted by #actions
	  (but cannot be 'gagged')
	* powwow can run in test-mode without being connected to a MUD

Changes from 0.5 to 0.6 (Massimiliano Ghilardi)
	* more debug work
	* #exe, #send and #print extended to use shell commands and files
	  Also, #send replaces #read
	* #time variable added
	* #rand function added
	* #connect now supports a different remote host for each connection
	  (i.e. you can now play on different MUDs with the same invocation
	  of powwow)

	Ideas coming from Cancan 2.5.1c and implemented on powwow 0.6:

	* output to the remote host is buffered up and sent all at once in the
	  main loop, to reduce the number of network packets. Long aliases
	  might benefit from this, as would repeated commands (#10 buy bread).
	* #help now works on commands. A help file is needed and provided.
	* new command: #record, records lines you type in a file
	* source changed so path for helpfile is taken from environment
	  variable POWWOWHELP (if this variable is not defined, powwow looks
	  in current directory)
	* to print the message of the day, must define MOTDFILE in compiling
	  with the name (and complete path) of the file containing the message
	* Now compiles on BSD/386 as well, automatically detected by make_it

Changes from 0.4 to 0.5 (Massimiliano Ghilardi)
	* Heavy debug work, since 0.4 was an alpha version
	  (it is not a good idea to place here the huge list of bugs fixed...)
	* added #history to list/execute commands in history
	  Note: #history commands are not placed in history...
	* now internal commands can be abbreviated, for example #al can be used
	  istead of #alias. However, internal commands are still completed
	  using TAB

Changes from Cancan 2.5.0b to powwow 0.4 (Massimiliano Ghilardi)
	* Inline calculator, with both global and local variables, and C-like
	  syntax
	* added commands #(), #print, #send, #exe to use inline calculator
	* added commands #if-#else, #for and #while.
	* added #key, #save, #load, #save, #lines, #info, #echo, #compact, 
	  #net, #clock, #time
	* added #in and #at to define/edit delayed commands
	* #mark and all attrib-related commands now accept also the attribute
	  'none'
	* #marks and #actions now are not automatically sorted (to sort them,
	  define SORT in compiling). #aliases and #binds instead are always
	  sorted.
	* #aliases can be self-recursive now (it is potentially dangerous,
	  powwow will not enter a very long - but not infinite - loop)
	* Must not escape ';' anymore to place multiple commands in #alias,
	  #action or #bind. Instead, multiple commands must be surrounded by
	  braces, { and }
	* #action changed syntax (not need double quotes anymore, but need one
	  of > < + - = before label) See powwow.doc for details
	  Lines matched with #action are not printed on screen automatically,
	  must use a #print to echo them
	* #gag is suppressed (not needed anymore), and #add is now a command
	* Escaping technique changed. Now unescaping '\\\#' gives '\\#' (i.e.
	  remove one \ each time), and you can also escape \, in this way:
	  \` gives \ alone, \`` gives \` and so on. So for example, if you
	  want to place a \ at the end of an #action pattern, you must write
	  \` , to avoid escaping the = after the pattern
	* Some bugs of Cancan fixed (small things, expecially wrapping)

Changes from 2.5.0a to 2.5.0b (Finn Arne Gangstad)
	* Fixed bug with client aborting when window wsa resized.

Changes from 2.5.0 to 2.5.0a (Finn Arne Gangstad)
	* Various tweaks to make it compile on most systems.

Changes from 2.4.4 to 2.5.0 (Mattias Engdegard)
	* the length of the prompt is now correctly calculated
	  even if it contains escape sequences (for muds with coloured prompt).
	* built-in commands are always completed with tab and aren't stored in
	  the word list
	* #hilite and #mark now accept general attributes: ansi colours and
	  bold, underline, inverse.
	* the #action command has changed syntax; now double quotes are
	  required around the pattern, but they can be named. Actions can be
	  turned on and off.
	* the keydefs list contains all keyboard bindings. The #bind command
	  can define new keys.
	* the #alias, #action, #bind and #mark commands can now put a
	  definition line in the input buffer for easy editing.
	  The keys M-p and M-n are no longer used.
	* some new files, new source module discipline with external
	  declarations only in header files.
	* added the file HACKING with some advice.
	* mapping functions cleaned up. #map now displays ssss as 4s.
	* the definition file is tagged with a file version, to make it easier
	  to recognize older save formats.
	* cancan now displays a motd file whose location is set at compile
	  time (see Makefile).
	* define TELNETBUG to work around an NCSA telnet 2.2 colour bug.
	  #stdcolour can be used to set the background colour if TELNETBUG is
	  defined.

Changes from 2.4.3 to 2.4.4 (David Gay)
	* telnet window size option supported

Changes from 2.4.2 to 2.4.3
        * added term support
	* added #hilite to hilite user entered text
	* added #mark and #unmark to mark special keywords...
	* changed #identify to allow it to send alias' or commands to the
	  mud when beginning/ending an editing session.
	* changes the Makefile a bit to support termcancan
	
Changes from 2.4.1 to 2.4.2
	* Added multiple-session support with following # commands:
	  '#connect', '#zap', '#snoop', '##'
	* Added numeric keypad movement, keypad sends commands
	  n,e,s,w,u,d and exits.. (not on all systems)
	* Easier editing of actions with meta-p and meta-n (not on all systems)
	* Changed the 'make_it' script a bit, so that it echoes the make
	  command it executes.

Changes from 2.4.1 to 2.4.1b
	* Improved modularity of source, new files cmd.c, cmd.h

Changes from 2.4.0 to 2.4.1
	* Changed & in actions to match a single word for backward
	  compatibility.  &0..&9 still match multi-worded text.
	* Now compiles on HP-UX (at least HP-UX 9.01A )
	* Included a 'make_it' script that automatically compiles cancan for
	  Linux, IRIX, AIX, ULTRIX, DolphinOS, SunOS and HP-UX sytems.

Changes from 2.3.6 to 2.4.0
	* Extended param substitution for & to &0..&9.
	* Added '&&' syntax for delayed param substitution.
	* Added '#init' command to send initialization string on connect.
	* Added '#speedwalk' to toggle speedwalk on and off.
	* Added '#map' with automapping.
	* Added '#retrace' to retrace steps.
	* Added sorting for alias and action lists, which is disabled if
	  compiled with -DNOSORT.
	* Added compile option -DNOSHELL to remove '#!' shell escape function.

Changes from Cancan 2.3.5 to 2.3.6
	* Fixed a bug with MUME's spinning delay bars and word wrap.
	* & can now be escaped. This allows for aliases that create aliases,
	  and other things.
	* Added this change log (not too early)
	* Checks the window size after being suspended, in case it was
	  changed.
	* Lines longer than screen width because of invisible spaces and/or
	  trailing CR:s are not unnecessarily wrapped.
