[editor's note: this commit combines approximate 4 months of furious

backup tapes from that era seem to be readable anymore.  I guess 13 years
exceeds the shelf life for that backup technology :-(.

-    There is now a pragma mechanism, using the keywords "aver" and "deny".
-    Current pragmas are "integer" and "strict".  Unrecognized pragmas
-    are ignored.
+    Several previously added features have been subsumed under the new
+    keywords "use" and "no".  Saying "use Module LIST" is short for
+       BEGIN { require Module; import Module LIST; }
+    The "no" keyword is identical except that it calls "unimport" instead.
+    The earlier pragma mechanism now uses this mechanism, and two new
+    modules have been added to the library to implement "use integer"
+    and variations of "use strict vars, refs, subs".
+
+    Variables may now be interpolated literally into a pattern by prefixing
+    them with \Q, which works just like \U, but backwhacks non-alphanumerics
+    instead.  There is also a corresponding quotemeta function.
+
+    Any quantifier in a regular expression may now be followed by a ? to
+    indicate that the pattern is supposed to match as little as possible.
+
+    Pattern matches may now be followed by an m or s modifier to explicitly
+    request multiline or singleline semantics.  An s modifier makes . match
+    newline.
+
+    Patterns may now contain \A to match only at the beginning of the string,
+    and \Z to match only at the end.  These differ from ^ and $ in that
+    they ignore multiline semantics.  In addition, \G matches where the
+    last interation of m//g or s///g left off.
+
+    Non-backreference-producing parens of various sorts may now be
+    indicated by placing a ? directly after the opening parenthesis,
+    followed by a character that indicates the purpose of the parens.
+    An :, for instance, indicates simple grouping.  (?:a|b|c) will
+    match any of a, b or c without producing a backreference.  It does
+    "eat" the input.  There are also assertions which do not eat the
+    input but do lookahead for you.  (?=stuff) indicates that the next
+    thing must be "stuff".  (?!nonsense) indicates that the next thing
+    must not be "nonsense".
+
+    The negation operator now treats non-numeric strings specially.
+    A -"text" is turned into "-text", so that -bareword is the same
+    as "-bareword".  If the string already begins with a + or -, it
+    is flipped to the other sign.
