+Version 2.0
+'GOOSEBERRY' release, 08/24/03
+
+Comments:
+In view of the cumulative changes in the last several updates, it's
+bumped up to a major version. This is now officially a "mature" project.
+
+
+
+1) In "Manipulating Strings" section of "Variables Revisited" chapter:
+   Added negative index substring extraction example (Thanks, Dan
+   Jacobson).
+
+2) In "Sed appendix":
+   Changed title of second table, to make it less ambiguous.
+
+3) Changed "Sunsite" address in two examples.
+
+4) Made capitalization of example scripts more consistent.
+
+5) In "Command Substitution" chapter:
+   Fixed typo in backquotes discussion (Thanks, Jiri Beran).
+
+6) In "Process Substitution" chapter:
+   Added clarifying comment to SuSE script fragment (Thanks Ulrich Gayer).
+
+7) In "Invoking the script" section of
+  "Starting Off With a Sha-Bang" chapter:
+   Corrected typo in discussion
+   (" . . . not recommended is using sh <scriptname . . . ")
+   (Thanks, Norman Megill.)
+
+8) In "Quoting" chapter:
+   Corrected typo in final example ("foor" --> "foo").
+   (Thanks, Norman Megill.)
+   Noted that 'echo "\" invokes secondary prompt.
+
+9) In "Here Document" chapter:
+   Shuffled the order of a couple of examples.
+   Added warning about closing 'limit string' starting in first character
+   position on its line, with in-line example. (Also added a mention in
+  "Gotchas" chapter.
+   Added "script-generate.sh" example of generating program code
+   by disabling parameter substitution within the body of a 'here document.'
+   (Thanks, Albert Reiner, for the idea.)
+
+10) In "Miscellaneous" subsection of "System and Administrative Commands"
+    chapter:
+    Added listing for "dialog" toolsets.
+
+11) In "Assorted Tips" section of "Miscellany" chapter:
+    Added discussion of "dialog" toolsets, with "dialog.sh" example.
+
+12) In "Copyright" chapter:
+    Updated notices.
+
+13) Added "Reference Cards" appendix.
+    Thank you, Aurelio Marinho Jargas, for giving me the inspiration.
+
+14) In "Bibliography" section:
+    Added LINUX JOURNAL article, "Scripting for X Productivity" listing.
+    Added Jargas' entry for "Regular Expression wizard."
+
+15) In "Loop Control" section of "Loops and Branches" chapter:
+    Embellished "symlinks.sh" example with Jean Helou's alternative
+    method.
+
+16) Typo fixes supplied by Edward Scholtz (thanks!):
+    "Special Variable Types" section of "Introduction to Variables" chapter
+        "fairly simply way" --> "fairly simple way"
+    "Quoting" chapter
+        "advisable in enclose it" --> "advisable to enclose it"
