+Changes from 1.2.4 to 1.2.5 (Massimiliano Ghilardi, ...) 21 Jan 2002
+ * Added append-mode to #capture: use #capture >file-name
+ * Cleaned #spawned commands interface: text they print on
+ standard output *MUST* terminate with a newline ('\n')
+ in order for powwow to execute it.
+ * Fixed missing #include <time.h> in main.h.
+ * Fixed broken matching of #mark patterns starting with $
+ * Added the following user-contributed patches:
+ * Put also 1-char lines into history;
+ * Do not capture/movie data coming from spawned commands;
+ * Fixed a bug in command parser.
+
+Changes from 1.2.3 to 1.2.4 (Massimiliano Ghilardi) 24 May 2000
+ * Added support for IAC GA as end-of-prompt marker.
+ * Added #request [prompt][editor][all]
+ * Fixed missing/slow prompt redrawing under some circumstances
+ if #isprompt <number> was used.
+
+Changes from 1.2.2 to 1.2.3 (Massimiliano Ghilardi) 18 Jan 2000
+ * Fixed `#spawn' command that was completely screwed up.
+ Also fixed CTRL-C not to kill spawned commands.
+ * Sending/receiving data to/from spawned commands erased the prompt
+ instead of reprinting it. Fixed.
+ (If you don't like powwow to show the prompt before executing
+ lines from spawned commands, set #option +compact)
+
+Changes from 1.2.1 to 1.2.2 (Massimiliano Ghilardi) 10 May 1999
+ * Fixed `#delim custom' to accept whatever character as delimiters.
+ Previously stopped before the first word-delimiting char (argh!)
+ * Fixed screen corruption when doing some editing functions
+ (&del-word-right, &del-word-left, &complete-word, &complete-line,
+ parentheses flashing) while data comes from the MUD.
+ * Fixed a line redrawing bug when inserting chars on terminals
+ with VT100-like wrapglitch.
+ * Fixed SEGFAULT on #send, #emulate, #exe of a numeric expression.
+ * Fixed stupid SEGFAULT when cancelling an editing session.
+ * Fixed sending/receiving latin-1 '\377' (ASCII char 255) as IAC IAC
+ to conform telnet protocol, both directly and inside MPI messages.
+ * Fixed matching #actions, #prompts and #marks on MUD data splitted
+ into multiple fragments.
+ * Fixed line length calculation when receiving '\r' in the middle
+ of a line.
+ * Fixed extra prompt redrawing in #option +compact mode.
+ * Added #option sendsize and #option autoclear.
+ Changed default not to send window size upon connecting.
+ (if the MUD asks it, the window size is sent anyway)
+ Use #option +sendsize to automatically send it when you connect.
+ * Added command #rawsend.
+ * Removed bits of ANSI code giving problems
+ with really picky non-ANSI compilers
+
+Changes from 1.2.0 to 1.2.1 (Massimiliano Ghilardi) 20 Nov 1998
+ * Fixed a typo in Makefile.
+ * Reversed order of saved #history lines.
+ * Fixed out-of-bound array accesses in tcp_find() and tcp_show()
+ which could give SEGFAULT on #connect, #snoop and #zap.
+ * Fixed buggy loop in saving #history in definition file that could
+ create a huge temporary file, filling the filesystem.
+ * Fixed sporadic SEGFAULT when hitting backspace and some other
+ editing keys.
+ * Math operator `?' could freeze due to buggy code.
+ Systems providing GNU memmem() didn't experience the problem
+ as it was used instead of my replacement code.
+ * Enhanced support for terminals with VT100-like wrapglitch:
+ on them, the rightmost character of every line is used too.
+ * Fixed wrapping in #printing strings containing ASCII chars > 127
+ when #option wrap is on.
+ * Fixed incorrect drawing of prompt and command line under some
+ circumstances.
+ * Fixed wrong wrapping of lines immediately after the prompt
+ in #option +wrap mode.
+ * Removed extra newlines sent after each line in `#send <filename'
+ and `send !command'.
+ * Fixed a few off-by-one errors causing corruption in #movie/#capture
+ and (reprint) buffers.
+ * Powwow now discards all \r received immediately before or after \n,
+ to avoid troubles when strange data comes just before the prompt.
+ * Changed MPI key to `unsigned int' because MUME uses a 32 bit
+ unsigned value for it.
+ * Cleaned up remote file editing not to leave stale files in /tmp.
+ * Cleaned up multiple connections support:
+ Fixed spurious `#too many open connections' errors.
+ Fixed prompt drawing glitches when getting data from subsidiary
+ connections.
+
+Changes from 1.1.7 to 1.2.0 (Massimiliano Ghilardi) 05 Oct 1998
+ * Copyright change. Powwow is now GPL-ed.
+ * Version number bump. I hope there aren't many bugs left.
+ If you are coming from 1.0.x versions, read this file and powwow.doc
+ carefully, many things have changed!
+ * Fixed double-newline printing after each line if #option +wrap
+ was set.
+ * Suppressed useless reprinting of files sent back to MUD
+ using MUME remote editing protocol.
+ * Updated a few details in docs.
+ * Some old compilers choked on bits of ANSI code. Fixed.
+ * Fixed extra newline after prompt in #movie and #capture
+ when #setvar buffer is not zero.
+ * Fixed extra \r at beginning of a line under rare circumstances.
+ * #delim now unescapes the custom delimeters.
+ * Added missing close() when remote host closes connection.
+ * Rewrote the code to merge lines received in two (or more) fragments.
+ * Added `#help warranty' and `#help copyright' to conform GPL :-/
+
+Changes from 1.1.6 to 1.1.7 (Massimiliano Ghilardi) 15 Sep 1998
+ * Changed meaning and effect of #prompt and #isprompt.
+ If you used them, re-read their docs in powwow.doc!
+ * Alias names containing spaces are now rejected too.
+ Relaxed rules a little, unbalanced () {} or ""
+ now just print a warning instead of causing an error.
+ * Added #option reprint.
+ * Old #prompts were not removed on #load. fixed.
+ * Fixed SEGFAULT when chaining very long strings:
+ #("foo..." + "bar...")
+ * Fixed small compiling problems on some platforms.
+ * Fixed an off-by-one error in math operator >:
+ * Fixed math operator `=' bug on copying empty strings.
+ * Fixed a crashy bug in #reset var.
+ * Fixed some quirks in unescaping strings:
+ ending backslashes caused SEGFAULT,
+ sequences like \\\``` were unescaped incorrectly.
+ * Fixed incorrect code in #mark and #action that
+ mismatched patterns containing two or more wildcards.
+
+Changes from 1.1.5 to 1.1.6 (Massimiliano Ghilardi) 03 Sep 1998
+ * Added circular backbuffer for #capture and #movie.
+ Can be enabled/disabled/resized with #setvar buffer.
+ * Sanitized aliases: powwow now rejects alias names containing
+ unbalanced special chars ""(){} . Example:
+ #alias (=#print is illegal, while
+ #alias "("=#print is ok.
+ #alias {}=#print is ok,
+ #alias \\{=#print is ok too as it matches \{ and _not_ {
+ * Removed a redundant alias unescaping. If #alias foo=\\bar
+ then `foo' now sends `\bar' instead of `bar'.
+ * Fixed a compatibility problem when reading #binds of new savefiles
+ using old versions of powwow.
+ * Fixed some problems with #var on numbered variables.
+ * Fixed #internal error, selflookup_sortednode() failed!
+ that affected 1.1.5
+ * Fixed SEGFAULT upon #exe \; (introduced in 1.1.5).
+ * When getting data from the MUD after a prompt which set #isprompt
+ the data is now printed as a separate line even if it doesn't start
+ with a newline. Helps turning things like
+ * HP:Fine>You hit the wolf's head hard.
+ into
+ * HP:Fine>
+ You hit the wolf's head hard.
+ Anyway, such data has _always_ been considered separate
+ from the prompt if it set #isprompt, i.e. #action patterns like
+ "^You hit the wolf" already worked in the above case.
+
+Changes from 1.1.4 to 1.1.5 (Massimiliano Ghilardi) 30 Aug 1998
+ * Massive code cleanup.
+ * Finished removing size limits on strings, text lines and variables.
+ * Renamed `#settimer' as `#setvar timer' and `#lines' as `#setvar lines'
+ Added `#setvar mem' to set/edit/remove length limit on text/strings.
+ * Powwow now stops command execution after any error.
+ * #key now works also with editing keys.
+ * Added #keyedit command. "#keyedit &prev-line" runs
+ the editing function `&prev-line' and so on.
+ * Added "&insert-string <string>" editing function.
+ * Added #mark ^pattern, which matches only at line start.
+ * Decreased CPU usage when/after a lot of variables, aliases or marks
+ are created.
+ * Added `*' and `*=' math operator for strings.
+ * Fixed math operators ^^=, ||= and &&= to always return 0 or 1.
+ * Fixed SEGFAULT when creating more than 100 variables.
+ (bug introduced in 1.1.0)
+ * Fixed SEGFAULT when realloc()ing very big strings.
+ * Fixed memory leaks when running out of memory.
+ * Fixed escaping/printing of nasty strings like
+ backslash + control char.
+ * Fixed some redrawing glitches on very long input lines.
+ Input lines bigger than the whole window are still not drawn
+ correctly. Same problem on prompts longer than a line.
+ * Fixed #prompts to fully work also on prompts received inside
+ a set of newline-terminated lines.
+ * Documented #prompt, #capture and #movie to work only for
+ the main MUD connection
+
+Changes from 1.1.3 to 1.1.4 (Massimiliano Ghilardi) 23 Jul 1998
+ * Renamed `movie_play' to `movie'. Will do the replay if invoked as
+ `movie_play' and will convert to ASCII if invoked as `movie2ascii'
+ * Fixed a 1.1.1 bug that could cause a lot of missed binds.
+ * Finished adding ANSI prototypes. Renamed some files and remixed
+ some code in the process.
+ * Removed -DUSE_TERMIO. If you used it, no problem.
+ If you didn't use it, you must now add -DUSE_SGTTY.
+ * Fixed a few compiling problems on OSF1 and other systems
+ with really annoying compilers.
+ * Fixed missing sig_oneshot on systems without SA_ONESHOT
+ * Fixed input of chars with high bit set (again).
+
+Changes from 1.1.2 to 1.1.3 (Massimiliano Ghilardi) 21 Jul 1998
+ * Variable names are now expressions too. This means that
+ @("foo"+"bar") is the variable @foobar.
+ * Added `just in time' substitution: ${varname} @{varname} and #{expr}
+ Not yet implemented for regexp patterns, sorry.
+ This introduces a subtle incompatibility with older versions,
+ as now also text coming from $n substitution gets unescaped.
+ Sorry again. (see powwow.doc for details).
+ * #action and #prompt did not work when using an expression
+ as pattern. Now fixed.
+ * Fixed small bug in anonymous actions. Someone still using them?
+ * powwow_help renamed powwow.help
+ * Fixed a bug in #alias: $1..$9 all contained the first word ($1)
+ * Fixed math operators . : .? :? .< .> <. >. :< :> <: >: which
+ segfaulted on empty strings (bug introduced in 1.1.0)
+ * Made SIGINT signal handler non-permanent to allow interrupting
+ system calls like connect(). Partially reverses the change in 0.9.3
+ * Undone a change Gustav made in 0.9.3: now #connect with no args
+ always lists the open connections. To open a new connection you must
+ give at least one argument, for example #connect main.
+ * Changed edit function &redraw-line not to clear prompt.
+ Use &redraw-line-noprompt to get the old behaviour.
+ * Added #movie command to record all output from the MUD
+ and local commands to a file, adding timestamps to allow replay
+ at correct speed. Also added `movie_play' standalone program
+ to actually do the replay.
+
+Changes from 1.1.1 to 1.1.2 (Massimiliano Ghilardi) 16 Jun 1998
+ * The wildcard `$' now correctly matches single words only
+ both in #actions and in #marks.
+ It was (again!) matching also multiple words like `&'
+ * Fixed up attr and noattr math operators, which broke in 1.1.0
+ * Added workaround for buggy terminals which create empty lines with
+ coloured background when using #hilite <whatever> on <colour>.
+ Must compile with -DBUG_ANSI to enable it.
+
+Changes from 1.1.0 to 1.1.1 (Massimiliano Ghilardi) 11 Jun 1998
+ * Added some changes from 1.0.1 that didn't go in 1.1.0.
+ The 1.0.x and the 1.1.x trees are indipendent...
+ * Wrote a memmem() replacement for systems that don't have it.
+ * Decreased CPU usage when receiving lots of text from the terminal
+ (for example using cut-n-paste)
+ * Continued adding ANSI prototypes.
+
+Changes from 1.0.0 to 1.1.0 (Massimiliano Ghilardi) 20 May 1998
+ * Splitted 1.0.x and 1.1.x source trees.
+ * Started adding ANSI function prototypes.
+ Old K&R compilers still work.
+ * Removed all size limits in all strings, text lines and variables.
+ Also allowed '\0' (ASCII zero) in strings.
+ It was a _huge_ task! Probably messed up all and everything.
+ * Side effect of the above: lines of arbitrary length received from
+ the MUD should now work perfectly (at least as long as you have
+ enough memory)
+
+Changes from 1.0.0 to 1.0.1 (Massimiliano Ghilardi) 18 May 1998
+ * Changed name of some files (Changelog, Hacking, Compile.how,
+ Config.demo)
+ * Fixed #capture and #record to save text from main connection only.
+ * Fixed a buffer overrun in $last_line when receiving lines longer
+ than 1024 chars. Hopefully lines up to 4095 chars will now work.
+ * Fixed message "Creating %s" when creating a new definition file.
+ * Added `catrw' standalone mini-program for splitting powwow output
+ in multiple windows (quick tutorial in powwow.doc, section #write)
+ * Added #rebindall and #rebindALL
+
+Changes from 0.9.9 to 1.0.0 (Massimiliano Ghilardi) 13 May 1998
+ * Disabled NAGLE for tcp connections (set TCP_NODELAY option)
+ which should hopefully increase performance during lossy conditions
+ (idea and code contributed by Finne Arne Gangstad)
+ * Cleaned up error handling. Powwow tries really hard to report
+ any system call error, quitting only when there is really no hope.
+ Anyway, if you get a '#system call error' message, you should
+ seriously consider quitting as soon as possible since either
+ the connection is messed up or your system is running
+ out of resources.
+ * Removed extra newline after prompt bug when in #option -compact mode,
+ introduced in 0.9.7
+ * Fixed $last_line to contain last non-empty line from the MUD.
+ * Updated config.demo with definitions for time-inside-prompt
+ and other things.
+
+Changes from 0.9.8 to 0.9.9 (Massimiliano Ghilardi) 12 May 1998
+ * Changed rx.h to regex.h in includes
+ * Fixed behaviour on prompts and lines received in multiple packets:
+ 0.9.7 and 0.9.8 sometimes print garbage.
+ * Added some flush()es in the code to cope with the new
+ terminal I/O buffering.
+
+Changes from 0.9.7 to 0.9.8 (Massimiliano Ghilardi) 11 May 1998
+ * Fixed compile problems on AIX (got out of sync).
+ * Fixed a stupid bug that caused all actions to be regexp
+ (introduced in 0.9.7)
+ * Introduced a more efficient terminal I/O buffering.
+
+Changes from 0.9.6 to 0.9.7 (Massimiliano Ghilardi) 11 May 1998
+ * Increased stability when receiving extremely long lines (>1024 bytes)
+ The fix is only partial, powwow can still crash on lines slightly
+ shorter than 4096 bytes when a lot of #marks are used.
+ * Cleaned up the names of various #defines
+ In particular, USETERMIO is now USE_TERMIO and
+ TELNETBUG is now BUG_TELNET
+ * Added #option autoprint, to automatically print lines matched
+ by #actions.
+ * Added #spawn command.
+ * Added #prompt command. Just like #action, but matches both on
+ prompts and on normal text.
+ * #actions now work differently on prompts:
+ prompts are not matched immediately against #actions,
+ but only after a \n arrives from the MUD, just in case they are
+ actually normal lines received in multiple packets and not prompts.
+
+ Thanks to the this change, powwow behaves better on lines received
+ in two (or more) packets.
+ See the file powwow.doc, section `#prompt' for the gory details.
+
+Changes from 0.9.5 to 0.9.6
+ (Gustav Hållberg, 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 Hållberg, 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 `#hilite' 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 Hållberg:
+ 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 regexp #actions from ']' to '%'
+
+Changes from 0.9.2 to 0.9.3 (Gustav Hållberg) 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 (Massimiliano: I never finished it...)),
+ 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 regexp)
+ 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 bound 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 purposes...
+ * #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
+ NO_RANDOM 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 was 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 Engdegård)
+ * 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.
+
