+version 0.8.5
+ - Fixed a couple lingering Unicode bugs, one of which was breaking things
+   pretty thoroughly under Python 2.2.3.
+ - Improved whitespace handling, to the point where it should be compliant
+   with the AIML 1.0.1 standard.  Basically, whitespace will be stripped
+   down to readable levels, unless the xml:space attribute is used to
+   indicate otherwise.
+ - Fixed bug in PatternMgr where the character '1' was mistaken identified
+   as punctuation to be stripped, instead of the intended '!'.
+
+version 0.8.4:
+ - Fixed bug in AimlParser creation, if the aiml module was not in the same
+   directory as the script that imported it.
+ - Improved Unicode support (again) (thanks to Daniel Kottow for his help).
+ - 2nd pass at documentation.  All functions now have useful, properly-formatted
+   docstrings.
+
+version 0.8.3:
+ - Reworked the way AimlParser objects are created, to allow support for
+   XML namespaces in a future version.
+ - First pass at Unicode-proofing the whole system, so that multi-lingual
+   AIML files can be processed.
+ - Added support for "index" attribute in "star", "thatstar" and "topicstar"
+   elements (thanks to Robert D. Cotey for the patch!).  Also added type-check
+   to ensure that the value of the "index" attribute is an integer.
+
+version 0.8.2:
+ - Added protection against infinite AIML recursion.
+ - Removed the deprecated Kernel.getBotName and Kernel.setBotName functions.
+ - Added workaround for Unicode input crash.  Feeding the Kernel Unicode
+   input no longer crashes the interpreter, but some internal input-formatting
+   operations must be skipped, which could cause some nonsensical replies
+   (like you're not already used to nonsensical replies, though...)
+
+version 0.8.1:
+ - "system" elements now attempt to intelligently convert between UNIX-style
+   and Windows-style pathnames as appropriate.  For cross-platform compatibility,
+   all AIML files should use UNIX-style paths inside their "system" elements.
+ - Fixed crashes under Windows9X when a "system" element is executed when
+   w9xpopen.exe is unavailable.
+ - Re-piped most errors and warnings to go to stderr instead of stdout.
+ - Fixed bug that would cause the the bot to stop responding to any input in a session
+   if the "that" or "topic" strings were 100% whitespace (but still not empty).
+ - Fixed bug that would cause multi-line "that" strings to become corrupted.  For
+   example, "Hello there.\nNice to meet you" would become "HELLO THERENICE TO MEET
+   YOU" when queried for that-matching.
+
+version 0.8:
+ - Removed support for non-standard "mode" attribute in "system" elements.
+   It just wasn't worth breaking the AIML standard for.
+ - Reworked persistent session support (I warned you!).  The old method involving
+   Kernel.persistentSessions() has been removed.  Instead, there is a new
+   Kernel.getSessionData() method which gives the bot author access to the session
+   data.  You can store this data however you wish.  Session data can be restored
+   later by repeated calls to Kernel.setPredicate().
+ - Improved AIML parser error handling; instead of aborting the entire file, a
+   parse error now only ignores the current category and forges ahead.  To check for
+   parse errors, check the return value of AimlParser.getNumErrors() after parsing.
+
+version 0.7:
+ - Further improved AIML parsing; missing or invalid XML attributes are now
+   detected at parse-time.  There's also a first stab at support for Forward
+   Compatibility Mode: if the "version" attribute of an AIML tag is not 1.0.1,
+   the parser is much more forgiving of unknown or missing XML tags and attributes.
+ - Added "support" for the 'gossip' tag.  The specific behavior of this tag is
+   totally undefined; currently, the PyAIML implementation treats it as a big
+   no-op.  Its contents are ignored, and it returns the empty string (but at least
+   it isn't flagged as a syntax error!) 
+ - Oops; I've implemented 'person' as 'person2' and vice versa this whole time!
+   Swapped them back; they should each behave correctly now.
+ - A bit of code cleanup, with an emphasis on using proper XML/AIML terminology
+   whenever possible.
+ - Fixed some exception-masking in the 'condition' element processor, which could
+   prevent AIML parse errors from being reported.
+ - Added full support for the "bot" tag (previously only the 'bot name="name"'
+   form was supported).  Bot predicates are set using the Kernel.setBotPredicate()
+   function.  Note that Kernel.getBotName() and Kernel.setBotName() have been
+   deprecated, and will disappear in a future release.
+
+version 0.6.1:
+ - Fixed undefined variable exception that was thrown whenever there was no
+   match for the user's input.
+ - Fixed an infinite recursion bug caused by processing two or more nested
+   'srai' or 'sr' elements.
+
+version 0.6
+ - Completely rewrote the LearnHandler class (which handles all AIML parsing)
+   to be much less forgiving of incorrect AIML.  Currently, any AIML errors
+   outside of "template" elements should be caught and reported at load-time.
+   AIML errors inside templates are still not detected until run-time.
+ - Added support for atomic 'person' and 'person2' tags (they implicitly use
+   'star' as their contents if none are provided).
+ - Oops; Kernel.respond() was DEFINITELY not thread-safe.  Now it is, provided
+   you're using Python's standard 'threading' module. If not, you'll have to
+   provide your own mutual-exclusion system to ensure that only one thread
+   is calling Kernel.respond() at a time.
+ - Recursive tags ('srai' and 'sr') no longer add their intermediate results
+   to the input and output history.
+ - EXPERIMENTAL FEATURE: persistent sessions.  If enabled using
+   Kernel.persistentSessions(True), session data will be written to disk
+   after every response.  This lets session data be preserved when the
+   Kernel is destroyed, at the expense of a small performance hit (all
+   that extra disk I/O).  The semantics of this feature may change in future
+   releases!
+ - Added support for the "id" tag (it returns the session ID).
+ - Added support for the "topic", "topicstar" and "thatstar" tags.
+ - Commented up the test.py file.
+ - Added a summary to the end of the Kernel.py self-test (since there are now
+   too many tests to fit on screen).
+ - Added support for multi-sentence input.  The user's input is split into
+   individual sentences, each of which is treated as a completely separate
+   piece of input.  I'm *pretty* sure this is the Right Way(tm).
+
+version 0.5
+ - The filename inside Learn tags can now contain wildcards.  Besides
+   simplifying the loading of multiple files, this allows the possibility
+   of loading AIML files that may not exist without crashing the
+   interpreter.
+ - Attempting to set the value of a predicate in a nonexistent session
+   now automatically creates the session, instead of silently doing nothing.
+ - "set" tags now output the new value of the variable, as well as assigning
+   it.
+
+version 0.4.1
+ - Unknown AIML tags are handled in a more forgiving fashion.  If an
+   unknown tag is encountered, instead of ignoring its contents entirely,
+   the contents are processed and returned unaltered.
+ - Added support for "bot name='name'" tags, both in patterns and in
+   templates.  This also fixes a nasty infinite loop crash when a user
+   says Hello to a bot. 
+
+version 0.4
+ - Added support for "star" and "sr" tags.
+ - Considered adding support for the "secure" tag, but decided against it.
+   see SUPPORTED_TAGS.txt for more information.
+
+version 0.3
+ - Cleaned up AIML processing code to remove some unnecessary
+   special-cases in the interpretation algorithm.
+ - Added support for "input" and "that" tags.
+
+version 0.2
+ - 50% speedup in Kernel.loadBrain() and Kernel.saveBrain().
+ - The optional 'learnFiles' and 'commands' arguments to
+   Kernel.bootstrap() can now be either strings or lists. This
+   allows multiple files/commands to be loaded during
+   initialization.
+ - Added support for "person" and "person2" tags.
+ - Added general word-substitution functionality.  This opens up
+   the potential for localizing PyAIML into non-English languages.
+   See DefaultSubs.py for more info.
+
+version 0.1:
+ - Initial release.

+PyAIML -- The Python AIML Interpreter
+author: Cort Stratton (cort@users.sourceforge.net)
+web: http://pyaiml.sourceforge.net/
+
+PyAIML is an interpreter for AIML (the Artificial Intelligence Markup
+Language), implemented entirely in standard Python.  It strives for
+simple, austere, 100% compliance with the AIML 1.0.1 standard, no less
+and no more.
+
+This is currently pre-alpha software.  Use at your
+own risk!
+
+For information on what's new in this version, see the
+CHANGES.txt file.
+
+For information on the state of development, including 
+the current level of AIML 1.0.1 compliance, see the
+SUPPORTED_TAGS.txt file.
+
+Quick & dirty example (assuming you've downloaded the
+"standard" AIML set):
+
+	import aiml
+
+	# The Kernel object is the public interface to
+	# the AIML interpreter.
+	k = aiml.Kernel()
+
+	# Use the 'learn' method to load the contents
+	# of an AIML file into the Kernel.
+	k.learn("std-startup.xml")
+
+	# Use the 'respond' method to compute the response
+	# to a user's input string.  respond() returns
+	# the interpreter's response, which in this case
+	# we ignore.
+	k.respond("load aiml b")
+
+	# Loop forever, reading user input from the command
+	# line and printing responses.
+	while True: print k.respond(raw_input("> "))

+This document describes the current state of PyAIML's compliance
+to the AIML 1.0.1 standard.  The full AIML reference manual can be
+found online at http://alicebot.org/TR/2001/WD-aiml.
+
+The following tags are currently supported:
+
+	<bot name="name"> (see notes)
+	<condition>
+	<date>
+	<formal>
+	<gender>
+	<get>
+	<id>
+	<input>
+	<learn>
+	<li>
+	<lowercase>
+	<person>
+	<person2>
+	<random>
+	<sentence>
+	<set>
+	<size>
+	<sr>
+	<srai>
+	<star>
+	<system>
+	<that>
+	<thatstar>
+	<think>
+	<topic>
+	<topicstar>
+	<uppercase>
+	<version>
+
+Support for the following tags should be implemented in the next version:
+
+	None
+
+The following tags are not supported:
+
+	<gossip> (see notes)
+	<if> / <else> (see notes)
+	<javascript> (see notes)
+	<secure> (see notes)
+
+------------------------------------------------------------------
+
+NOTES ON SPECIFIC TAGS:
+
+<bot name="name">
+To set the bot's name, use Kernel.setBotName("NewName").  Note that the
+name *MUST* be a single word!  Use Kernel.getBotName() to query the bot's
+name in your code.
+
+<gossip>
+The AIML 1.0.1 specification lets engine authors implement the the behavior
+of the <gossip> tag however they wish.  I haven't yet decided what I'd like
+to do with it, so right now it doesn't do anything at all.
+
+<if> / <else>
+These elements appear to have been dropped between AIML 1.0 and AIML 1.0.1.
+They may someday be added as a part of an AIML 1.0 backwards-compatibility
+mode, but in the meantime, use <condition> instead.
+
+<javascript>
+Support for the JavaScript tag is not anticipated; one of the design
+goals of PyAIML is to remain 100% pure standard Python.  So until
+somebody writes a JavaScript interpreter in Python, PyAIML won't
+support the <javascript> tag.  On the bright side, it is possible
+to simulate the effects of the <javascript> tag (i.e. dynamically-
+generated tag contents) using the <system mode="sync"> tag.  This
+solution has the added advantage of allowing *any* programming
+language to be used, not just JavaScript.
+UPDATE: The python-spidermonkey project provides a bridge between Python
+and the open-source SpiderMonkey JavaScript library.  I am currently
+investigating the possibility of adding support for the <javascript>
+tag ON A PURELY OPTIONAL BASIS.
+
+<secure>
+Some AIML implementations support a non-standard <secure> tag, intended to
+wrap parts of a template which should only be processed if the user is
+"secure", or trusted.  After implementing support for this tag, I realized
+that it wasn't doing anything that you can't do with the <condition> tag.
+Therefore, I've decided to drop support for the <secure> tag.  You can
+easily duplicate its effects; simply replace this:
+	<secure error="you're not allowed">you are allowed</secure>
+with this:
+	<condition name="secure">
+		<li value="yes">you are allowed</li>
+		<li>you are not allowed</li>
+	</condition>
+Then, use the Kernel.setPredicate() call to set the "secure" predicate to
+"yes" for any session that you wish to be secure.

+Laundry list of future tasks, in no particular order:
+
+ - AIML 1.0.1 compliance (highest priority):
+   - Unknown yet well-defined elements (e.g. HTML) inside templates
+     (see sections 3.2, 3.6).
+   - AimlParser._validateElemStart() needs to test the well-formedness of
+     attribute values (for example, making sure that the "index" attribute
+     has an integer value, and not a string).  UPDATE: this works for <star>,
+     <thatstar> and <topicstar>.  Still needs to be written for <input> and <that>,
+     which take either an integer or an integer pair.
+ - Support the Program D startup file syntax, or something similar?  It
+   seems to be a good way to initialize bot settings and substitutions.
+ - Documentation/tutorials.
