+MICROSOFT WINDOWS
+=================
+
+I used to prohibit porting Remind to Microsoft Windows.  However, this
+may cause problems with the GPL, so I have removed that restriction.
+
+Although I cannot prevent you from porting Remind to Windows, I appeal
+to you not to do it.  I am trying to encourage the growth of free
+software, not proprietary software.
+
+If you port Remind to Windows, I will not provide support or answers to
+questions -- you're on your own.  On the other hand, I will feel no guilt
+in taking enhancements and merging them into the UNIX stream.
+
+APPLE
+=====
+
+I can't prevent you from using Remind on Apple's products, but I hope
+you don't.  Apple's corporate culture is the very antithesis of Free
+Software.  Rather than using Mac OS X, I encourage you to switch to
+Linux or FreeBSD, two Free Software operating systems that are every
+bit as capable as Mac OS X and which are unencumbered by Apple's
+arbitrary restrictions.
+
+And if you're looking to port Remind to other Apple products like the
+iPhone or iPad, please don't.  Those products enforce Apple's rigorous
+controls much more stringently than Mac OS X on an Apple PC.

+
+=item B<-man>
+
+Print the manual page and exit.
+
+=item B<-do>
+
+Actually do the conversion.  Otherwise just print a brief help message
+and usage example, and then exit.
+
+=item B<-norecur>
+
+Do not attempt to detect and fold together recurring events.
+
+=item B<-usetag>
+
+Generate UIDs using remind TAG clauses.

+
+Input is from standard input
+
+Output is to standard output.
+
+=head1 USAGE
+
+  remind -s360 -irem2ics=1 ~/.reminders 1 Jan 1991 | TZ=PST8PDT rem2ics -do >reminders.ics
+
+This tells B<remind> to use ~/.reminders, and to process the entire
+range of dates it can handle (from Jan 1 1991 to Dec 31 2020), and to
+define a variable named C<rem2ics>, which can be used in
+C<IF !defined("rem2ics")> / C<ENDIF> pairs.
+B<rem2ics> will use a timezone of PST8PDT, and will fold events that
+have the same name and duration into a single iCalendar VEVENT object.
+
+=head1 NOTES
+
+=head2 Timezones and the TZ environment variable.
+
+B<rem2ics> uses the TZ environment variable to determine the value of
+the RFC2445 TZID property.  If you are running on a Linux or other GNU
+libc based system, you probably don't (and probably shouldn't)
+normally have TZ set.  You can confirm this by running C<printenv TZ>
+at a shell prompt.  If your remind data is in your "local time", and
+it probably is, you should probably set TZ to a good name for your
+local timezone just for the run of this script.  You probably should
+NOT set TZ in your login scripts.
+
+You can use TZ like this:
+
+  remind -s ~/.reminders | TZ=PST8PDT rem2ics -do >reminders.ics
+
+or
+
+  remind -s ~/.reminders | TZ=US/Pacific rem2ics -do >reminders.ics
+
+
+If, for some reason, your remind files are all in GMT instead of
+localtime (you smart person you!), you can do this:
+
+  remind -s ~/.reminders | TZ=GMT rem2ics -do >reminders.ics
+
+or
+
+  remind -s ~/.reminders | TZ=0 rem2ics -do >reminders.ics
+
+and B<rem2ics> will use the ISO8601 "Z" notation for GMT time in the ics
+file.  (Other synonyms for GMT are the empty string (not the same as
+the TZ not set), "I<0>", "I<Z>", "I<Zulu>", "I<Greenwitch>", "I<GMT>",
+"I<GMT+0>, and "I<GMT-0>".)
+
+If you leave TZ undefined and unset, B<rem2ics> will use the ISO8601
+"T" notation date strings with no TZID property, which RFC2445 calls a
+"floating time".  Who knows, it might work for you!
+
+The TZ string value is literally incorporated into the iCalendar
+stream, so whatever your iCalendar-using application needs is what you
+should use.  You may have to experiment a bit.
+
+You can look around in C</usr/share/zoneinfo> to get the names of
+every timezone anywhere.  This is the "Olson database" that RFC2445
+refers to.  Read the man page for L<tzfile(5)> for more than you ever
+wanted to know about the format of these files, and about GNU libc's
+handling of timezones.  As complex as it is, it's certainly better
+than what POSIX defines or what most legacy UNIX systems do, and most
+certainly better than Microsoft, who in their "cutting edge" "state of
+the art" "server" OS, still hasn't figured out that daylight time
+rules might be different in different years.
+
+If you just ran B<rem2ics> without reading all this stuff, or if you
+don't want to worry about it at all, and somehow your iCalendar
+application manager is able to guess the proper timezone for you, just
+leave TZ undefined, and B<rem2ics> will use the ISO8601 "T" notation
+date strings with no TZID property, which RFC2445 calls a "floating
+time".  Who knows, it might work for you!
+
+=head2 Detecting recurring events
+
+B<rem2ics> tries to detect recurring events.  If any multiple events
+appear with exactly the text and exactly the same duration (including
+"no duration"), instead of multiple VEVENT objects, there will be just
+one VEVENT object, that will have a RFC2445 C<RDATE> property.
+
+B<rem2ics> is not yet smart enough to derive an C<RRULE> based
+recurrance.  If you really want that feature, either implement it and
+send in a patch, or contact the author and convince him to do it.
+
+=head2 Other iCalendar Properties
+
+B<rem2ics> does not generate C<DESCRIPTION> or C<LOCATION>.  One
+would have to heuristically parse them out of the text, and everyone
+uses a idiosyncratic way of putting things in B<remind>.
+
+If the B<-usetag> option is not used or no C<TAG> is set for a
+reminder, B<rem2ics> will synthesize C<UID> properties for each
+VEVENT, but the UIDs will be different (and unique) for each run of
+B<rem2ics>.  If you run rem2ics twice and import the two resulting ICS
+streams into your new scheduling program, your appointments will
+appear twice.  If, however, you have set C<TAG> clauses in your
+reminders and activated B<-usetag>, these will be used.  The same
+applies for tags synthesized by B<remind>'s B<-y> option.  Hence, it
+is more useful to use the B<-y> option than to let B<rem2ics>
+synthesize UIDs, because the UIDs will stay the same across multiple
+runs.
+
+=head2 Other iCalendar Perl objects
+
+Why does't B<rem2ics> use any of the iCalendar Perl stuff in CPAN?
+Because I don't trust them, and they are too big for this app.  One
+links to a binary library. Another hasn't been maintained since 1991,
+and is full of notes as to how buggy and incomplete it is.  And so
+forth.  I am not at this moment interested in groveling around in
+L<Net::iCal>, L<DateTime::Format::iCal>, L<Tie::iCal>,
+L<iCal::Parser>, or C<libical>.
+
+=head2 Previous implementation
+
+There is a working quick & dirty rem2ics written in awk
+by Anthony J. Chivetta E<lt>achivetta@gmail.comE<gt>.
+
+But it has the following problems: it doesn't escape the text, it
+doesn't handle events that cross over midnight, it doesn't do
+timezones, it doesn't enforce the correct EOL sequence, and it doesn't
+fold long lines.  This is a replacement for that script.
+
+=head1 TODO
+
+ If TZ not set, grab out of system config somewhere
+ Detect recurring events.
+  If I'm REALLY smart, derive RRULE
+ Handle characters not in US-ASCII. Latin1? UTF8?

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+

+
+;;; Commentary:
+
+;; Use this mode to help with the configuration of remind configuration files.
+;; Put (require 'remind-conf-mode) in your .emacs file
+;; or (autoload 'remind-conf-mode "remind-conf-mode" "Mode to help with remind files" t)
+;; also put (add-to-list 'auto-mode-alist '("\\.rem\\'" . remind-conf-mode)) and
+;; (setq auto-mode-alist
+;;     (cons '(".reminders$" . remind-conf-mode) auto-mode-alist))
+;; if you want to have the mode work automatically when you open a remind configuration file.
+
+;; If you want to use the auto-complete stuff, you will need to download and install the
+;; auto-complete library from  http://www.cx4a.org/pub/auto-complete.el and put
+;; (require 'auto-complete) in your emacs with
+;; (add-hook 'remind-conf-mode-hook
+;;  (lambda ()
+;;    (make-local-variable 'ac-sources)
+;;    (setq ac-sources '(ac-remind-conf ac-remind-builtin-variables ac-remind-builtin-functions))
+;;    (auto-complete t)))
+;;   in your .emacs file
+
+;;   PS. you could add ac-source-abbrev ac-source-words-in-buffer to have abbrevs and
+;;   other words in buffer auto-complete too
+
+;;; History:
+;; Thu, Feb 14, 2008
+;; Based mode on wpld-mode tutorial and sample-mode on emacs wiki.
+;; Ideas from mupad.el for font-lock styles.
+;; Mon, Jan 26, 2008
+;; Added rem-setup-colors to make it easy for colourised remind output.
+;; Added a demo skeleton for people to copy for easy entry of coloured remind entries.
+;; tried to hook in the auto-complete library so that all known functions and keywords can be easily entered.
+;; EXPERIMENTAL, but seems to work well here (emacs cvs).
+;; Seems to work without case folding which is nice. wonder why it didn't yesterday?
+
+;;; Code:
+
+
+(require 'font-lock); this goes in the define-derived-mode part.
+(when (featurep 'xemacs)
+  (require 'overlay)) ;I wonder if this will help with font-lock and xemacs?

 CHANGES TO REMIND
 
+* VERSION 3.3 Patch 9 - 2021-10-14
+
+- NEW FEATURE: Add "-+username" option to tell Remind to trust files owned by
+  "username" and allow RUN directives in them.  Idea courtesy of Ian! D. Allen
+
+- NEW FEATURE: Add "-u+username" variant to tell Remind to switch users to
+  "username" without disabling RUN directices.  Idea courtesy of Ian! D. Allen
+
+- CHANGE: rem2html: rem2html has been moved out of the www/ directory into
+  its own rem2html/ directory.  If your system has the prerequisites
+  (namely Perl, Getopt::Long and JSON::Any) then rem2html will be installed
+  by "make install".
+
+- CHANGE: Remove "cm2rem".  It was about 20 years obsolete.
+
+- CHANGE: rem2html: Use inline data: URL images for moon images by default,
+  thus producing a completely stand-alone HTML file.
+
+- CHANGE: Remove unnecessary spaces from "remind -pp" JSON output.
+
+- DOCUMENTATION FIX: Various man page fixes and tweaks.
+
+- BUG FIX: rem2html: Tweak the default CSS stylesheet; more rational
+  handling of rem2html command-line options.
+
+- BUG FIX: remind: "remind -c" would sometimes highlight *two* days as
+  "today"; this has been fixed.
+
+- BUG FIX: Add a missing #ifdef...#endif and remove a C99-ism.  This once again
+  allows Remind to be compiled with some very old C compilers.
+
+* VERSION 3.3 Patch 8 - 2021-09-13
+
+- NEW FEATURE: remind: Add INCLUDECMD command
+
+- NEW FEATURE: remind: Add shellescape() built-in function
+
+- BUG FIX: tkremind: TkRemind would sometimes fill in incorrect initial
+  values for the reminder-editing form if you clicked on a TkRemind-created
+  reminder to edit it.  This has been fixed.
+
+- BUG FIX: tkremind: Get back better error messages from Remind if you
+  try to create a reminder with an invalid date specification.
+
+- BUG FIX: remind: Catch integer overflow if we try to evaluate $IntMin * -1
+
+- DOC UPDATES: remind: Minor man page fixes
+
+* VERSION 3.3 Patch 7 - 2021-05-10
+
+- MINOR FIX: Refuse to run "make test" as root --- it would fail
+  anyway with an obscure message.
+
+- BUG FIX: Remind would sometimes compute incorrect trigger date for:
+  REM Tue 29 Feb MSG ...
+
+- BUG FIX: Remind would sometimes compute incorrect trigger date for
+  a date spec like: Tue 31 2021 MSG ...
+
+* VERSION 3.3 Patch 6 - 2021-03-30
+
+- test/test.rem: Change local to en_US.utf-8 only if current locale
+  is not a UTF-8 locale.
+
+- MINOR CHANGE: Remind's arithemtic operators (+, -, *, /) give errors
+  on overflow rather than silently giving the wrong answer.
+
+- MINOR CHANGE: Add $IntMin and $IntMax system variables.
+
+- DOCUMENTATION FIX: Document that TkRemind now requires Tcl/Tk version
+  8.5 or newer.
+
+* VERSION 3.3 Patch 5 - 2021-01-21
+
+- NEW FEATURE: tkremind: Add ability to change fonts and colors from
+  within TkRemind "Options" dialog.
+
+- CHANGE: tkremind: TkRemind now requires Tcl/Tk 8.5 or newer.
+
+- CHANGE: tkremind: You can specify the location of the options
+  file on the command-line if you want to use one other than ~/.tkremindrc
+
+- CLEANUP: tkremind: Remove "Apply Options" from Options dialog; we only
+  need "Save Options".
+
+- DOC FIX: Add missing release note in 3.3.4 notes regarding
+  setpagedevice patch
+
+- DOC FIX: tkremind: Document shortcut keys.
+
+* VERSION 3.3 Patch 4 - 2021-01-12
+
+- NEW FEATURE: If "inotifywait" is installed, TkRemind uses it to refresh
+  the calendar display right away when the reminders file/directory is updated.
+  This makes TkRemind react almost instantly if external tools are editing
+  or updating reminders.
+
+- MINOR NEW FEATURE: rem2ps has a new '-x' option; this puts the day numbers
+  on the top-left of the day's box instead of the top-right.
+
+- MINOR FIXES: A typo in remind.1 was fixed; additional comments regarding
+  UNTIL were added.
+
+- BUG FIX: rem2ps: Call setpagedevice to set page size.  Based on a patch
+  from Jonathan Kamens.
+
+* VERSION 3.3 Patch 3 - 2020-11-09
+
+- BUG FIX: Fix startup crash in TkRemind if "Show Today's Reminders on
+  Startup" is enabled (which, unfortunately, is the default.)  Bug reported
+  by Martin Ziemer.
+
+* VERSION 3.3 Patch 2 - 2020-11-08
+
+- MINOR NEW FEATURE: Add MAYBE-UNCOMPUTABLE keyword; see the man page
+  and discussion at
+  https://dianne.skoll.ca/pipermail/remind-fans/2020/003745.html
+
+- CHANGE: TkRemind always invokes Remind with the "-itkremind=1" option,
+  even when printing.  NOTE INCOMPATIBILITY: This is a behavior change!
+  When you print from TkRemind, we also invoke Remind with "-itkprint=1"
+  so you can detect that PostScript is being generated.
+
+- CHANGE: The maxmimum length of a variable name has been increased from
+  16 characters to 64 characters.  Modern computers have plenty of memory.
+
+- BUG FIXES: Minor documentation updates, typo fixes, clarifications, etc.
+
+- BUG FIX: Fix calendar-drawing alignment errors when displaying UTF-8
+  strings with zero-width combining characters and strings with tabs.
+
+- BUG FIX: TkRemind would mess up placement of the WEEK special if invoked
+  with the "-m" option.  This has been fixed.
+
+- BUG FIX: TkRemind would sometimes fail with an error message when editing
+  a reminder; this is because it was interpreting months 08 and 09 as
+  illegal octal numbers.  This has been fixed.
+
+* VERSION 3.3 Patch 1 - 2020-03-20
+
+- CHANGE: For overlapping multi-day events, issue a reminder for the
+  most *recent* event rather than the earliest event.  NOTE
+  INCOMPATIBILITY: This is a behavior change!
+
+- CHANGE: Do not convert 90-99 to 1990-1999 when parsing numbers to
+  recognize years.  NOTE INCOMPATIBILITY: This is a behavior change!
+
+- CHANGE: Revert change to -y option that included filename and line
+  number in the hash.
+
+- CHANGE: Retain newlines (produced by %_) in JSON output.
+
+- FIX: Document $FormWidth system variable
+
+- FIX: Highlight today's date in "remind -c" output
+
+- FIX: Eliminate compiler warnings on Ubuntu 18.04.
+
+- IMPROVEMENT: Allow times to be specified either in 24-hour mode
+  (HH:MM or HH.MM) or AM/PM mode (HH:MMam; HH:MMpm, etc.)
+
+- IMPROVEMENT: Allow DURATION to be specified as a time (1:30) or a
+  number of minutes (90).
+
+- IMPROVEMENT: If terminal size can be determined, set $FormWidth to
+  terminal width - 8; if not, set $FormWidth to 72.
+
+- MINOR IMPROVEMENT: Add the "ampm()" built-in function.
+
+* Version 3.3 Patch 0 - 2020-01-31
+
+- FIX: rem2ps: Add a %%PageBoundingBox: document structuring convention
+  comment.
+
+- FIX: rem2ps: Ignore unknown SPECIAL-type reminders.
+
+- IMPROVEMENT: In calendar mode ("-c" option), Remind automatically adjusts
+  the width of the calendar to fit the terminal window if standard output
+  is a TTY.
+
+- IMPROVEMENT: Add JSON-based output with "remind -pp" and "remind -ppp"
+  The JSON-based intermediate format preserves a lot more information
+  about the original reminder, allowing back-ends more insight into
+  the intent of the reminder, the recurrence used, etc.  See the documentation
+  in "man rem2ps"
+
+- IMPROVEMENT: TkRemind can "reverse-engineer" reminders that it creates
+  using the additional information in the "remind -pp" format, so it
+  doesn't create or use ugly comment blocks to delimit the reminders
+  it creates.
+
+- IMPROVEMENT: TkRemind: Add popup help to most buttons and controls.
+
+- NEW FEATURE: Add support for $DefaultColor system variable, suggested
+  by Tim Chase.
+
+- NEW FEATURE: The "-@[n][,m]" command-line option allows colored reminders
+  in Agenda Mode as well as in Calendar Mode.  It also adds support for
+  terminal emulators that can handle the xterm 256-color escape sequences
+  as well as the true 24-bit color escape sequences.
+
+- CHANGE: SPECIALs are now case-insensitive.  Before, only SPECIAL COLOR
+  would work.  Now you can use Special Color, special color, etc.
+
+* Version 3.2 Patch 0 - 2020-01-03
+
+- IMPROVEMENT: Add support for events spanning multiple days (with AT
+  and DURATION).  Add trigeventstart() and trigeventduration()
+  introspection functions; see "MULTI-DAY EVENTS" in the man page.
+
+- IMPROVEMENT: Add introspection functions trigback(), trigdelta(),
+  trigduration(), trigfrom(), trigpriority(), trigrep(),
+  trigscanfrom(), trigtimedelta(), trigtimerep(), and triguntil().  See
+  man page for details; thanks to Tim Chase for the suggestion.
+
+- IMPROVEMENT: TkRemind: Use PNG images for the next month / previous
+  month buttons rather than -> and <-.  Also use nice anti-aliased
+  moon phase images instead of ugly blocky bitmaps.
+
+- CHANGE: Modify addition so that previously-illegal combinations
+  TIME + TIME, TIME + DATETIME and DATETIME + TIME are now allowed.
+  Also allow DATETIME - TIME.  If t1 and t2 are expressions of type TIME
+  and dt is an expression of type DATETIME, then the following are now
+  equivalent (before, the expressions on the left-hand side would fail
+  with a "Type mismatch" error.)
+
+  t1 + t2     ==     t1                + coerce("INT", t2)
+  dt + t2     ==     dt                + coerce("INT", t2)
+  t1 + dt     ==     coerce("INT", t1) + dt
+  dt - t2     ==     dt                - coerce("INT", t2)
+
+- DOC FIX: Document previously-undocumented $MaxStringLen system variable
+
+- DOC FIX: Various minor documentation fixes.
+
+- BUG FIX: Specifying a DURATION without an AT clause results in an error.
+  Before, it would be accepted but not do anything useful.
+
+- BUG FIX: Catch potential date overflow in slide() function
+
+- BUG FIX: Fix compile error when compiling Romanian version; eliminate
+  compiler warning when compiling non-English versions.
+
+- BUG FIX: TkRemind: Fix startup failure of TkRemind if options are at
+  default. :(
+
+* Version 3.1 Patch 17 - 2019-11-15
+
+- IMPROVEMENT: Add "Extra Remind Options" setting to TkRemind.
+
+- IMPROVEMENT: Enable warning-free compilation even with gcc -Wextra flag.
+
+- IMPROVEMENT: Warn if "OMIT a THROUGH b" has a > b.
+
+- SYNTACTIC SUGAR: Make "SCANFROM -n" the same as "SCANFROM [today() - n]"
+
+- BUG FIX: Don't dump expired reminders when dumping queue.
+
+- BUG FIX: Fix failure when specifying a Jahrzeit in Adar.  Fix
+  courtesy of Dov Feldstern
+
+- BUG FIX: Fix various documentation errors and update man page.
+
+* Version 3.1 Patch 16 - 2018-11-09
+
+- IMPROVEMENT: Add patch from Stephen Morgan to calculate astronomical and
+  nautical twilight in addition to civil twilight.
+
+- BUG FIX: The rem2html script correctly handles a SHADE special with only
+  one number (a grey level).
+
+- IMPROVEMENT: Remind accepts DATETIME constants in ISO-8601 format and can
+  optionally be configured to output them that way too.
+
+- MINOR IMPROVEMENT: TkRemind puts its hostname in the window title bar.
+
+- MINOR IMPROVEMENT: TkRemind restarts the background remind daemon if
+  the .reminders file changes
+
+- MINOR IMPROVEMENT: TkRemind has a "Queue" button that lets you see details
+  of upcoming queued reminders.  This is mostly for debugging and the output
+  is not particularly readable.
+
+- BUG FIX: The definitions form Yom Hazikaron and Yom Ha'atzmaut were not
+  quite right; they have been fixed.
+
+- MINOR IMPROVEMENT: TkRemind centers popups over the main calendar
+  window rather than over the desktop background.  This is better
+  behavior in multi-monitor setups.
+
+- BUG FIX: In "remind -z0" mode, remind wakes up exactly on the minute instead
+  of sleeping for 60 seconds each time, which could cause it to fall behind.
+
+* Version 3.1 Patch 15 - 2015-07-27
+
+- BUG FIX: Fix a buffer overflow found by Alexander Keller
+
+- BUG FIX: Fix a typo in this file: was 2014 instead of 2015.
+
+- BUG FIX: Make parser reject an AT followed by more than one time.
+
+- BUG FIX: Make parser reject epeated delta or *repeat values.
+
+* Version 3.1 Patch 14 - 2015-04-24
+
+- NEW FEATURE: Putting the line __EOF__ in a .rem file causes Remind
+  to treat it as end-of-file.
+
+- IMPROVEMENT: Use better PNG images for moons in the HTML display
+
+- CHANGE: Author name updated from "David" to "Dianne"
+
+- BUG FIX: The "-n" command-line option should really run in "ADVANCE_MODE"
+  rather than "CAL_MODE" internally; otherwise, the substitution sequences
+  may be misinterpreted.
+
+- BUG FIX: A typo in clearing out MD5 sum context has been fixed.
+
+- BUG FIX: Typo in Spanish translation was fixed.
+
+* Version 3.1 Patch 13 - 2013-03-22
+
+- BUG FIX: Sunrise/Sunset calculations greatly improved thanks to John
+  McGowan.  Accuracy should now be within a couple of minutes in most
+  places.
+
+- BUG FIX: Allow specification of margins as low as 0 points in rem2ps,
+  courtesy of Jonathan Kamens.
+
+- BUG FIX: Permit compilation with gcc 2.95 (which doesn't allow variable
+  declarations after non-declaration statements in a block.)
+
+- BUG FIX: Several minor documentation errors corrected courtesy of
+  Simon Ruderich.
+
+- BUG FIX: Spurious test harness failure was fixed.
+
+* Version 3.1 Patch 12 - 2012-01-23
+
+- NEW FEATURE: Many substitution sequences "%x" have an alternate mode
+  denoted by "%*x".  This alternate mode leaves out prepositions.  For
+  example, in English "%i" might yield "on 01-25" while "%*i" yields only
+  "01-25".
+
+- BUG FIX: The "dusk" and "dawn" calculations were completely wrong.  They
+  have been fixed.  Also, sunrise/sunset calculations have been tweaked,
+  so the results may be off by a minute or two compared to previous versions
+  of Remind.
+
+* Version 3.1 Patch 11 - 2011-12-16
+
+- BUG FIX: For some inexplicable reason, dawn was considered to happen when
+  the sun was 14 degrees below the horizon instead of the standard 6
+  degrees for Civil Dawn.  This has been fixed.
+
+- BUG FIXES: Clarified the man pages and fixed some typos.
+
+- BUG FIX: Add THROUGH to the remind.vim syntax highlighting file.
+
+- ENHANCEMENT (?): Allow SPECIAL COLOR to be spelled SPECIAL COLOUR.
+
+- BUG FIX: Apply minor Debian cleanups reported by Kurt B. Kaiser.
+
+* Version 3.1 Patch 10 - 2010-11-01
+
+- NOTE: This is the 20th anniversary of Remind's first public release.
+
+- ENHANCEMENT: Add the THROUGH keyword.  You can omit blocks of dates with:
+
+  OMIT start THROUGH end
+
+  and the syntax REM start THROUGH end is equivalent to REM start *1 UNTIL end
+
+- ENHANCEMENT: Add support for multibyte characters (eg, UTF-8) in calendar
+  output.  Note that UTF-8 strings are still not supported in PostScript
+  output.
+
+- ENHANCEMENT: Add support for UTF-8 line-drawing characters in calendar
+  output.
+
+- ENHANCEMENT: You can have multiple TAG clauses in a REM statement.
+
+- BUG FIX: Avoid spawning long-running background processes in "make test".
+
+- BUG FIX: Don't declare variables in the middle of statements (old C
+  compilers choke.)
+
+* Version 3.1 Patch 9 - 2010-06-20
+
+- MAJOR ENHANCEMENT: New "purge mode" to delete expired reminders.  See
+  the PURGE MODE section of the remind man page.
+
+- ENHANCEMENT: Support DURATION in TkRemind.  Thanks to Marek Marczykowski.
+
+- BUG FIX: Don't change the order of PS and PSFILE reminders.  Bug found
+  by John McGowan.
+
+- BUG FIX: "REM 1990-01-01 SATISFY 1" would yield a spurious parse error
+  in earlier versions of Remind.
+
+- BUG FIX: Yom HaShoah is moved to Thursday if it would normally fall on
+  a Friday.  Thanks to Jonathan Kamens for pointing this out.
+
+* Version 3.1 Patch 8 - 2010-03-09
+
+- ENHANCEMENT: Include some useful scripts in contrib/
+
+- ENHANCEMENT: Add the $T, $Td, $Tm, $Tw, $Ty, $U, $Ud, $Um, $Uw, $Uy
+  special variables to make reminder files less wordy.  See man page
+  for details.
+
+- MINOR ENHANCEMENT: Set an icon photo window manager resource on TkRemind.
+
+- POLICY CHANGE: Discourage use of Remind on MS Windows or Apple Mac OS X.
+
+- BUG FIX: Ignore msgprefix() and msgsuffix() on RUN-type reminders.
+
+- BUG FIX: Adjust Remind and Rem2PS so that SHADE specials don't obliterate
+  earlier MOON specials.
+
+- BUG FIX: Fix bug in SCHED calculations if Remind is started in the middle
+  of a SCHED interval.

+rem2html requires the Perl modules `JSON::Any' and `Getopt::Long'.  It
