+## How I use Remind and Google Calendar together
+
+  - My family has a Google Email domain, and our email addresses all end in the same domain. We all use Google Calendars and I want to mail reminders to each of the family members containing both Google Calendar and .reminder information.
+  - Under my ~/.rem/ directory each family member has a directory.  Each directory contains a standard remind file called 'reminders' that at the very least has the line "INCLUDE /home/jalcorn/.rem/<username>/ical2rem" and flag files indicating whether they want Daily or Weekly reminders.  My reminders files references my standard .reminders file, and I also have a flag so if I run a Test run I'll get it.  There's actually a lot more files (I have a big family).

+  - bin/getgooglecals.sh runs out of crontab and downloads whatever calendars I want. Note that we can also download organization calendars, I've included a public one here (Cleveland Heights Vocal Music Department calendar).
+  - dailyreminders.sh is linked to weeklyreminders.sh and testreminders.sh so I can run it in different modes. The concatenate the various calendar outputs as a single remind file then send the reminders via email.
+### Example: .rem/son1/reminders file:
+````

+## Revision History
+### Version 0.7 2024-09-04
+  - ISSUE 8: New version of remind complains if _sfun isn't defined. Output a header
+	to define a function that does nothing if the function doesn't exist.
+### Version 0.6 2019-03-01
+  - Publish on GitHub and change license to MIT License
+  - Add supporting files and explanation of how I use it
+### version 0.5.2 2007-03-23
+      - BUG: leadtime for recurring events had a max of 4 instead of DEFAULT_LEAD_TIME
+      - remove project-lead-time, since Category was a non-standard attribute
+      - NOTE: There is a bug in iCal::Parser v1.14 that causes multiple calendars to
+              fail if a calendar with recurring events is followed by a calendar with no
+              recurring events.  This has been reported to the iCal::Parser author.
+### version 0.5.1 2007-03-21
+      - BUG: Handle multiple calendars on STDIN
+      - add --heading option for priority on section headers
+### version 0.5 2007-03-21
+      - Add more help options
+      - --project-lead-time option
+      - Supress printing of heading if there are no todos to print
+### version 0.4
+      - Version 0.4 changes all written or inspired by, and thanks to Mark Stosberg
+      - Change to GetOptions
+      - Change to pipe
+      - Add --label, --help options
+      - Add Help Text
+      - Change to subroutines
+      - Efficiency and Cleanup
+### version 0.3
+      - Convert to GPL (Thanks to Mark Stosberg)
+      - Add usage
+### version 0.2
+      - add command line switches
+      - add debug code
+      - add SCHED _sfun keyword
+      - fix typos
+### version 0.1 - ALPHA CODE.

 CHANGES TO REMIND
 
+* VERSION 5.0 Patch 5 - 2024-09-02
+
+* CHANGE: remind: When using the "-c" option and with the SHADE special
+  enabled, shade the entire calendar box including the line containing the
+  day number.
+
+* IMPROVEMENT: remind: Better error messages when diagnosing certain
+  errors in expressions.
+
+* IMPROVEMENT: include/holidays/jewish.rem: Remove unnecessary _h()
+  function definition.
+
+* BUG FIX: remind: In a couple of spots when we parsed a character, we did
+  not check for an error return.  This has been fixed.
+
+* BUG FIX: remind: Fix edge-case bugs in "remind -c" output formatting.
+
+* BUG FIX: make test: Fix a test that was broken for all of September 2024.
+
+* BUG FIX: remind: Fix a couple of potential file-descriptor leaks.
+
+* BUG FIX: contrib/ical2rem.pl: Replace "SCHED _sfun" with "+15" to
+  hard-code 15-minutes advance warning rather than using an undefined
+  scheduling function.  If this is not what you want, you should edit
+  ical2rem.pl to suit your taste; it's not officially part of Remind and
+  is meant more as a starting point for you to customize than a finished
+  product.
+
+* DOCUMENTATION FIX: Remove obsolete info from Remind man page.
+
 * VERSION 5.0 Patch 4 - 2024-08-29
 
 * IMPROVEMENT: remind: When checking if a SATISFY expression refers to the
