+Revision history for Perl extension Text::Soundex.
+
+3.02 Sun Feb 02 02:54:00 EST 2003 <mark@mielke.cc>
+
+The U8 type was over-used in 3.00 and 3.01. Now, "U8 *" is used only as a
+pointer into the UTF-8 string. Also, unicode now works properly on
+Perl 5.6.x as the utf8_to_uv() function is used instead of utf8n_to_uvchr()
+when compiled under a version of Perl earlier than 5.8.0.
+
+3.01 Sun Jan 26 16:30:00 EST 2003 <mark@mielke.cc>
+
+A bug with non-UTF 8 strings that contain non-ASCII alphabetic characters
+was fixed. The soundex_unicode() and soundex_nara_unicode() wrapper
+routines were included and the documentation refers the user to the
+excellent Text::Unidecode module to perform soundex encodings using
+unicode strings. The Perl versions of the routines have been further
+optimized, and correct a border case involving non-alphabetic characters
+at the beginning of the string.
+
+3.00 Sun Jan 26 04:08:00 EST 2003 <mark@mielke.cc>
+
+Updated documentation, simplified the Perl interface, and updated
+the XS code to be faster, and to properly work with UTF-8 strings.
+UNICODE characters outside the ASCII range (0x00 - 0x7F) are
+considered to be non-alphabetic for the purposes of the soundex
+algorithms.
+
+2.10 Sun Feb 15 15:29:38 EST 1998 <mark@mielke.cc>
+
+I've put in a version of my XS code and fully integrated it with the
+existing 100% perl mechanism. The change should be virtually transparent
+to the user. XS code is approx 7.5 times faster.
+ - Mark Mielke
+
+2.00 Thu Jan 1 16:22:11 1998 <mike@stok.co.uk>
+
+Incorporated Mark Mielke's rewritten version of the main soundex routine
+and made the test.pl file simpler.

+Text::Soundex Version 3.02
+
+NOTE: Users of Text::Soundex Version 2.x should consult the 'History'
+ section at the end of this document before installing this module.
+ The interface has been simplified, and existing code that takes
+ advantages of Version 2.x features may need to be altered to function
+ properly.
+
+This is a perl 5 module implementing the Soundex algorithm described by
+Knuth. The algorithm is used quite often for locating a person by name
+where the actual spelling of the name is not known.
+
+This version directly supercedes the version of Text::Soundex that can be
+found in the core from Perl 5.8.0 and down. (This version is a drop-in
+replacement)
+
+The algorithm used by soundex() is NOT fully compatible with the
+algorithm used to index names for US Censuses. Use the soundex_nara()
+subroutine to return codes for this purpose.
+
+Basic Usage:
+
+ Soundex is used to do a one way transformation of a name, converting
+ a character string given as input into a set of codes representing
+ the identifiable sounds those characters might make in the output.
+
+ For example:
+
+ use Text::Soundex;
+
+ print soundex("Mark"), "\n"; # prints: M620
+ print soundex("Marc"), "\n"; # prints: M620
+
+ print soundex("Hansen"), "\n"; # prints: H525
+ print soundex("Hanson"), "\n"; # prints: H525
+ print soundex("Henson"), "\n"; # prints: H525
+
+ In many situations, code such as the following:
+
+ if ($name1 eq $name2) {
+ ...
+ }
+
+ Can be substituted with:
+
+ if (soundex($name1) eq soundex($name2)) {
+ ...
+ }
+
+Installation:
+
+ Once the archive has been unpacked then the following steps are needed
+ to build, test and install the module (to be done in the directory which
+ contains the Makefile.PL)
+
+ perl Makefile.PL
+ make
+ make test
+
+ If the make test succeeds then the next step may need to be run as root
+ (on a Unix-like system) or with special privileges on other systems.
+
+ make install
+
+ If you do not want to use the XS code (for whatever reason) do the following
+ instead of the above:
+
+ perl Makefile.PL --no-xs
+ make
+ make test
+ make install
+
+ If any of the tests report 'not ok' and you are running perl 5.6.0 or later
+ then please contact Mark Mielke <mark@mielke.cc>
+
+History:
+
+ Version 3.02:
+ 3.01 and 3.00 used the 'U8' type incorrectly causing some strict
+ compilers to complain or refuse to compile the XS code. Also, unicode
+ support did not work properly for Perl 5.6.x. Both of these problems
+ are now fixed.
+
+ Version 3.01:
+ A bug with non-UTF 8 strings that contain non-ASCII alphabetic characters
+ was fixed. The soundex_unicode() and soundex_nara_unicode() wrapper
+ routines were included and the documentation refers the user to the
+ excellent Text::Unidecode module to perform soundex encodings using
+ unicode strings. The Perl versions of the routines have been further
+ optimized, and correct a border case involving non-alphabetic characters
+ at the beginning of the string.
+
+ Version 3.00:
+ Support for UTF-8 strings (unicode strings) is now in place. Note
+ that this allows UTF-8 strings to be passed to the XS version of
+ the soundex() routine. The Soundex algorithm treats characters
+ outside the ascii range (0x00 - 0x7F) as if they were not
+ alphabetical.
+
+ The interface has been simplified. In order to explicitly use the
+ non-XS implementation of soundex():
+
+ use Text::Soundex ();
+ $code = Text::Soundex::soundex_noxs($name);
+
+ In order to use the NARA soundex algorithm:
+
+ use Text::Soundex 'soundex_nara';
+ $code = soundex_nara($name);
+
+ Use of the ':NARA-Ruleset' import directive is now obsolete. To
+ emulate the old behaviour:
+
+ use Text::Soundex ();
+ *soundex = \&Text::Soundex::soundex_nara;
+ $code = soundex($name);
+
+ Version 2.20:
+ This version includes support for the algorithm used to index
+ the U.S. Federal Censuses. There is a slight descrepancy in the
+ definition for a soundex code which is not commonly known or
+ recognized involved similar sounding letters being seperated
+ by the characters H or W. This is defined as the NARA ruleset,
+ as this descrepency was discovered by them. (Calling it "the
+ US Census ruleset" was too unwieldy...)
+
+ NARA can be found at:
+ http://www.nara.gov/genealogy/
+
+ The algorithm requested by NARA can be found at:
+ http://home.utah-inter.net/kinsearch/Soundex.html
+
+ Ways to use it in your code:
+
+ Transparently change existing code like this:
+ =============================================
+ use Text::Soundex qw(:NARA-Ruleset);
+
+ ... soundex(...) ...
+
+ --
+
+ Make the change visibly distinct like this:
+ ===========================================
+ use Text::Soundex qw(soundex_nara);
+
+ ... soundex_nara(...) ...
+
+ Version 2.00:
+ This version is a full re-write of the 1.0 engine by Mark Mielke.
+ The goal was for speed... and this was achieved. There is an optional
+ XS module which can be used completely transparently by the user
+ which offers a further speed increase of a factor of more than 7.5X.
+
+ Version 1.00:
+ This version can be found in the perl core distribution from at
+ least Perl 5.8.0 and down. It was written by Mike Stok. It can be
+ identified by the fact that it does not contain a $VERSION
+ in the beginning of the module, and as well it uses an RCS
+ tag with a version of 1.x. This version, before some perl5'ish
+ packaging was introduced, was actually written for perl4.
