version 1.1
	o Made some major performance improvements.  Matches in loops
	are now twice as fast as before.

	o Slightly modified backslash behavior in substitute() so that
	you can specify "s#/#\\\\#g" to change /a/b/c to \a\b\c rather
	than \\a\\b\\c as is currently done.  The problem was that
	you could not specify that a single backslash at the end of a
	substituted string because it would always be interpreted to
	escape the delimiter.  We introduce the special case that a double
	backslash preceding the delimiter in the substituted string
	represents a single backslash.  All other double backslashes
	(actually a quadrupled sequence in the Java String) continue to
	represent two backslashes.

	o Updated to use OROMatcher 1.0.7

version 1.0.2
	o Fixed preMatch() and postMatch() methods to function correctly
	when a PatternMatcherInput instance has a begin offset greater than
	0 and an end offset less than the length of its associated input.
	Previously the methods assumed a begin offset of 0 and an end offset
	equal to the length of the input which worked for most cases.

	o Updated to use OROMatcher 1.0.5

version 1.0.1
	o Made PerlTools self-contained, including necessary OROMatcher and
	TextTools classes.  

	o MalformedCachePatternException and PatternCache moved into
	TextTools package.

	o PatternCache implemenations are generalized and moved into TextTools.
	This will require some minor code changes if you were directly using
	caches.

version 1.0
	o Class files now also included in a jar archive.  This is done
	as a convenience, but also so that Macintosh users can use the
	package.  PerlTools contains class filenames exceeding 31 characters
	in length, which exceeds the System 7 filename length limit,
	rendering the package in the form of unarchived class files 
	unusable on the Mac.

version 1.0b3
	o The smx modifiers are now allowed for patterns used with substitute()
         (s/pattern/replacement/[i][g][m][o][s][x]) in Perl5Util.
	This had been accidentally omitted in version 1.0b2.

version 1.0b2
	o Perl5Util now implements the MatchResult interface for convenience.

	o Added preMatch(), postMatch(), preMatchCharArray() and
	postMatchCharArray() methods to Perl5Util.  These methods may
	migrate into MatchResult in a future version of OROMatcher, but
	it's not clear yet if/when this will happen.
