 # $Log: fetch.pl.new,v $
+# Revision 1.28  2020/06/10 21:14:31  nick
+# Updated for w3 validation.
+#
+# Revision 1.27  2019/04/15 12:50:23  nick
+# The script was unable to handle html '&' and convert it, so I added that.  I probably should see if there's a library or something that handles all those automagically but I just tossed a regex in there for now that does the trick.
+#
+# Revision 1.26  2018/04/22 14:03:54  nick
+# Changed the default for Sunday comics that was causing issues with some comics.
+#
+# Revision 1.25  2018/02/12 13:30:58  nick
+# Added an easier to compare date string to determine if the status json file was updated today and report if it wasn't.
+#
+# Revision 1.24  2018/02/06 14:31:06  nick
+# A status report is now generated in JSON that can easily be scanned so that
+# I can be alerted when there are failures that I miss if I don't read the
+# comics that day.
+#
+# Revision 1.23  2018/01/26 13:05:27  nick
+# Added a new config option to remove all newline from the resulting index.html
+# file.  This allows for easier parsing for certain comics.  I then updated
+# the URLs to search for and enabled the newline removal for a handful
+# of uComics.
+#
+# I believe I've also properly fixed the Comic Config version displayed on
+# the webpage itself.
+#
+# Revision 1.22  2017/12/05 13:37:40  nick
+# Added the CVS config version to the outpuit.
+#
+# Revision 1.21  2015/10/26 14:25:40  nick
+# Fixed a bug that was improperly including the day of week string preventing the weekend comics from fetching proproperly.
+#
+# Revision 1.20  2015/10/22 12:58:44  nick
+# Added the ability for Sunday only comics.  Stonesoup is no longer weekdays, this has been added to Sunday only.  I also added Foxtrot Classics for weekdays and Foxtrot for Sundays.
+#
 # Revision 1.19  2015/07/13 12:56:58  nick
 # Added Sally Forth and Pearls Before Swine.  Adding Sally Forth required a change in the 'wget' command for fetching the index file to include 'user-agent' and 'referer'.
