-Boost Regex Library
-============================
-
-The Boost Regex library provides regular expression support for C++, this library is the ancestor to std::regex and still goes beyond
-and offers some advantages to, the standard version.
-
-The full documentation is available on [boost.org](http://www.boost.org/doc/libs/release/libs/regex/index.html).
-
-## Standalone Mode ##
-
- This library may now be used in "standalone" mode without the rest of the Boost C++ libraries, in order to do this you must either:
-
-* Have a C++17 compiler that supports __has_include, in this case if <boost/config.hpp> is not present then the library will automoatically enter standalone mode. Or:
-* Define BOOST_REGEX_STANDALONE when building.
-
-The main difference between the 2 modes, is that when Boost.Config is present the library will automatically configure itself around various compiler defects. In particular in order to use the library with exception support turned off, you will either need a copy of Boost.Config in your include path, or else manually define BOOST_NO_EXCEPTIONS when building.
-
-In any event, to obtain a standalone version of this library, simply download a .zip of the "master" branch of this repository.
-
-## Support, bugs and feature requests ##
-
-Bugs and feature requests can be reported through the [Gitub issue tracker](https://github.com/boostorg/regex/issues)
-(see [open issues](https://github.com/boostorg/regex/issues) and
-[closed issues](https://github.com/boostorg/regex/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aclosed)).
-
-You can submit your changes through a [pull request](https://github.com/boostorg/regex/pulls).
-
-There is no mailing-list specific to Boost Regex, although you can use the general-purpose Boost [mailing-list](http://lists.boost.org/mailman/listinfo.cgi/boost-users) using the tag [regex].
-
-
-## Development ##
-
-Clone the whole boost project, which includes the individual Boost projects as submodules ([see boost+git doc](https://github.com/boostorg/boost/wiki/Getting-Started)): 
-
-    git clone https://github.com/boostorg/boost
-    cd boost
-    git submodule update --init
-
-The Boost Regex Library is located in `libs/regex/`. 
-
-### Running tests ###
-First, make sure you are in `libs/regex/test`. 
-You can either run all the tests listed in `Jamfile.v2` or run a single test:
-
-    ../../../b2                        <- run all tests
-    ../../../b2 regex_regress          <- single test

-[section:bad_expression bad_expression]
-
-[h4 Synopsis]
-
-   #include <boost/pattern_except.hpp>
-
-The class `regex_error` defines the type of objects thrown as exceptions to 
-report errors during the conversion from a string representing a regular 
-expression to a finite state machine.  
-
-   namespace boost{
-
-   class regex_error : public std::runtime_error
-   {
-   public:
-      explicit regex_error(const std::string& s, regex_constants::error_type err, std::ptrdiff_t pos);
-      explicit regex_error(boost::regex_constants::error_type err);
-      boost::regex_constants::error_type code()const;
-      std::ptrdiff_t position()const;
-   };
-
-   typedef regex_error bad_pattern; // for backwards compatibility
-   typedef regex_error bad_expression; // for backwards compatibility
-   
-   } // namespace boost
-
-[h4 Description]
-
-   regex_error(const std::string& s, regex_constants::error_type err, std::ptrdiff_t pos);
-   regex_error(boost::regex_constants::error_type err);
-
-[*Effects:] Constructs an object of class regex_error.
-
-   boost::regex_constants::error_type code()const;
-
-[*Effects:] returns the error code that represents parsing error that occurred.
-
-   std::ptrdiff_t position()const; 
-
-[*Effects:] returns the location in the expression where parsing stopped.
-
-Footnotes: the choice of `std::runtime_error` as the base class for `regex_error` 
-is moot; depending upon how the library is used exceptions may be either 
-logic errors (programmer supplied expressions) or run time errors 
-(user supplied expressions).  The library previously used `bad_pattern` 
-and `bad_expression` for errors, these have been replaced by the single 
-class `regex_error` to keep the library in synchronization with the 
-[tr1].

-[section:basic_regex basic_regex]
-
-[h4 Synopsis]
-
-   #include <boost/regex.hpp>
-
-The template class `basic_regex` encapsulates regular expression 
-parsing and compilation. The class takes two template parameters:
-
-* `charT`: determines the character type, i.e. either `char` or `wchar_t`; 
-see [link boost_regex.ref.concepts.charT_concept charT concept].
-* `traits`: determines the behavior of the character type, for example which 
-character class names are recognized. A default traits class is provided: 
-`regex_traits<charT>`.  See also 
-[link boost_regex.ref.concepts.traits_concept traits concept].
-
-For ease of use there are two typedefs that define the two standard 
-`basic_regex` instances, unless you want to use custom traits classes or 
-non-standard character types (for example see 
-[link boost_regex.ref.non_std_strings.icu unicode support]), 
-you won't need to use anything other than these:
-
-   namespace boost{
-
-   template <class charT, class traits = regex_traits<charT>  >
-   class basic_regex;
-   
-   typedef basic_regex<char>      regex;
-   typedef basic_regex<wchar_t>   wregex;
-
-   }
-
-The definition of `basic_regex` follows: it is based very closely on class 
-`basic_string`, and fulfils the requirements for a constant-container of `charT`.
-
-   namespace boost{
-
-   template <class  charT, class traits = regex_traits<charT> >
-   class basic_regex {
-      public:          
-      // types:
-      typedef          charT                                value_type;
-      typedef          implementation-specific              const_iterator;
-      typedef          const_iterator                       iterator;                 
-      typedef          charT&                               reference;

-[section:captures Understanding Marked Sub-Expressions and Captures]
-
-Captures are the iterator ranges that are "captured" by marked 
-sub-expressions as a regular expression gets matched.  Each marked 
-sub-expression can result in more than one capture, if it is matched 
-more than once.  This document explains how captures and marked 
-sub-expressions in Boost.Regex are represented and accessed.
-
-[h4 Marked sub-expressions]
-
-Every time a Perl regular expression contains a parenthesis group `()`, it 
-spits out an extra field, known as a marked sub-expression, 
-for example the expression:
-
-[pre (\w+)\W+(\w+)]
-
-Has two marked sub-expressions (known as $1 and $2 respectively), in 
-addition the complete match is known as $&, everything before the 
-first match as $\`, and everything after the match as $'.  So 
-if the above expression is searched for within `"@abc def--"`, then we obtain:
-
-[table
-[[Sub-expression][Text found]]
-[[$\`]["@"]]
-[[$&]["abc def"]]
-[[$1]["abc"]]
-[[$2]["def"]]
-[[$']["--"]]
-]
-
-In Boost.Regex all these are accessible via the [match_results] class that 
-gets filled in when calling one of the regular expression matching algorithms 
-([regex_search], [regex_match], or [regex_iterator]).  So given:
-
-   boost::match_results<IteratorType> m;
-
-The Perl and Boost.Regex equivalents are as follows:
-
-[table 
-[[Perl][Boost.Regex]]
-[[$\`][`m.prefix()`]]
-[[$&][`m[0]`]]
-[[$n][`m[n]`]]
-[[$\'][`m.suffix()`]]
-]
-
-In Boost.Regex each sub-expression match is represented by a [sub_match] object, 
-this is basically just a pair of iterators denoting the start and end 
-position of the sub-expression match, but there are some additional 
-operators provided so that objects of type [sub_match] behave a lot like a 
-`std::basic_string`: for example they are implicitly convertible to a 
-`basic_string`, they can be compared to a string, added to a string, or 
-streamed out to an output stream.
-
-[h4 Unmatched Sub-Expressions]
-
-When a regular expression match is found there is no need for all of the 
-marked sub-expressions to have participated in the match, for example the expression:
-
-[pre (abc)|(def)]
-
-can match either $1 or $2, but never both at the same time.  In Boost.Regex 
-you can determine which sub-expressions matched by accessing the 
-`sub_match::matched` data member.
-
-[h4 Repeated Captures]
-
-When a marked sub-expression is repeated, then the sub-expression gets 
-"captured" multiple times, however normally only the final capture is available, 
-for example if
-
-[pre (?:(\w+)\W+)+]
-
-is matched against
-
-[pre one fine day]
-
-Then $1 will contain the string "day", and all the previous captures will have 
-been forgotten.
-
-However, Boost.Regex has an experimental feature that allows all the capture 
-information to be retained - this is accessed either via the 
-`match_results::captures` member function or the `sub_match::captures` member 
-function.  These functions return a container that contains a sequence of all 
-the captures obtained during the regular expression matching.  The following 
-example program shows how this information may be used:
-
-   #include <boost/regex.hpp>
-   #include <iostream>
-
-   void print_captures(const std::string& regx, const std::string& text)
-   {
-      boost::regex e(regx);
-      boost::smatch what;
-      std::cout << "Expression:  \"" << regx << "\"\n";
-      std::cout << "Text:        \"" << text << "\"\n";
-      if(boost::regex_match(text, what, e, boost::match_extra))
-      {
-         unsigned i, j;
-         std::cout << "** Match found **\n   Sub-Expressions:\n";
-         for(i = 0; i < what.size(); ++i)
-            std::cout << "      $" << i << " = \"" << what[i] << "\"\n";
-         std::cout << "   Captures:\n";
-         for(i = 0; i < what.size(); ++i)
-         {
-            std::cout << "      $" << i << " = {";
-            for(j = 0; j < what.captures(i).size(); ++j)
-            {
-               if(j)
-                  std::cout << ", ";
-               else
-                  std::cout << " ";
-               std::cout << "\"" << what.captures(i)[j] << "\"";
-            }
-            std::cout << " }\n";
-         }
-      }
-      else
-      {
-         std::cout << "** No Match found **\n";
-      }
-   }
-
-   int main(int , char* [])

-         "now is the time for all good men to come to the aid of the party");
-      return 0;
-   }
-

-Unfortunately enabling this feature has an impact on performance 
-(even if you don't use it), and a much bigger impact if you do use it, 
-therefore to use this feature you need to:
-
-* Define BOOST_REGEX_MATCH_EXTRA for all translation units including the library source (the best way to do this is to uncomment this define in boost/regex/user.hpp and then rebuild everything.
-* Pass the match_extra flag to the particular algorithms where you actually need the captures information (regex_search, regex_match, or regex_iterator).

-
-You shouldn't need to do anything special to configure Boost.Regex for use 
-with your compiler - the [@../../../config/index.html Boost.Config subsystem] should already take care of it, 
-if you do have problems (or you are using a particularly obscure compiler 
-or platform) then [@../../../config/index.html Boost.Config] has a configure script that you can run.

-[section:standalone Use in Standalone Mode (without the rest of Boost)]
-
-This library may now be used in "standalone" mode without the rest of the Boost C++ libraries,
-in order to do this you must either:
-
-* Have a C++17 compiler that supports `__has_include`, in this case if `<boost/config.hpp>` is *not* present
-then the library will automoatically enter standalone mode.  Or:
-* Define BOOST_REGEX_STANDALONE when building.
-
-The main difference between the 2 modes, is that when Boost.Config is present the library will automatically
-configure itself around various compiler defects.  In particular in order to use the library with exception support
-turned off, you will either need a copy of Boost.Config in your include path, or else manually define BOOST_NO_EXCEPTIONS
-when building.

-[[BOOST_REGEX_BLOCKSIZE][Boost.Regex uses largish blocks of memory to act as a stack for the state machine, the larger the block size then the fewer allocations that will take place.

-[[BOOST_REGEX_MAX_BLOCKS][Tells Boost.Regex how many blocks of size BOOST_REGEX_BLOCKSIZE it is permitted to use.  If this value is exceeded then Boost.Regex will stop trying to find a match and throw a std::runtime_error.

-[[BOOST_REGEX_MAX_CACHE_BLOCKS][Tells Boost.Regex how many memory blocks to store in 
-         it's internal cache - memory blocks are taken from this cache rather than by calling 
-         ::operator new.  Generally speaking this can be an order of magnitude faster than 
-         calling ::opertator new each time a memory block is required, but has the 
-         downside that Boost.Regex can end up caching a large chunk of memory (by default 
-         up to 16 blocks each of BOOST_REGEX_BLOCKSIZE size).  If memory is tight then try 
-         defining this to 0 (disables all caching), or if that is too slow, then a value of 
-         1 or 2, may be sufficient.  On the other hand, on large multi-processor, 
-multi-threaded systems, you may find that a higher value is in order.]]

-[section:faq FAQ]
-
-[*Q.] I can't get regex++ to work with escape characters, what's going on?
-
-[*A.] If you embed regular expressions in C++ code, then remember that escape 
-characters are processed twice: once by the C++ compiler, and once by the 
-Boost.Regex expression compiler, so to pass the regular expression \d+ 
-to Boost.Regex, you need to embed "\\d+" in your code. Likewise to match a 
-literal backslash you will need to embed "\\\\" in your code.
-
-[*Q.] No matter what I do regex_match always returns false, what's going on?
-
-[*A.] The algorithm regex_match only succeeds if the expression matches *all*
-of the text, if you want to *find* a sub-string within the text that matches
-the expression then use regex_search instead.
-
-[*Q.] Why does using parenthesis in a POSIX regular expression change the 
-result of a match?
-
-[*A.] For POSIX (extended and basic) regular expressions, but not for perl regexes, 
-parentheses don't only mark; they determine what the best match is as well. 
-When the expression is compiled as a POSIX basic or extended regex then Boost.Regex 
-follows the POSIX standard leftmost longest rule for determining what matched. 
-So if there is more than one possible match after considering the whole expression, 
-it looks next at the first sub-expression and then the second sub-expression 
-and so on. So...
-
-"'''(0*)([0-9]*)'''" against "00123" would produce
-$1 = "00"
-$2 = "123"
-
-where as
-
-"0*([0-9])*" against "00123" would produce
-$1 = "00123"
-
-If you think about it, had $1 only matched the "123", this would be "less good" 
-than the match "00123" which is both further to the left and longer. If you 
-want $1 to match only the "123" part, then you need to use something like:
-
-"0*([1-9][0-9]*)"
-
-as the expression.
-
-[*Q.] Why don't character ranges work properly (POSIX mode only)?
-
-[*A.] The POSIX standard specifies that character range expressions are 
-locale sensitive - so for example the expression [A-Z] will match any 
-collating element that collates between 'A' and 'Z'. That means that for 
-most locales other than "C" or "POSIX", [A-Z] would match the single 
-character 't' for example, which is not what most people expect - or 
-at least not what most people have come to expect from regular 
-expression engines. For this reason, the default behaviour of Boost.Regex 
-(perl mode) is to turn locale sensitive collation off by not setting the 
-`regex_constants::collate` compile time flag. However if you set a non-default 
-compile time flag - for example `regex_constants::extended` or 
-`regex_constants::basic`, then locale dependent collation will be enabled, 
-this also applies to the POSIX API functions which use either 
-`regex_constants::extended` or `regex_constants::basic` internally. 
-[Note - when `regex_constants::nocollate` in effect, the library behaves 
-"as if" the LC_COLLATE locale category were always "C", regardless of what 
-its actually set to - end note].
-
-[*Q.] Why are there no throw specifications on any of the functions? 
-What exceptions can the library throw?
-
-[*A.] Not all compilers support (or honor) throw specifications, others 
-support them but with reduced efficiency. Throw specifications may be added 
-at a later date as compilers begin to handle this better. The library 
-should throw only three types of exception: [boost::regex_error] can be 
-thrown by [basic_regex] when compiling a regular expression, `std::runtime_error` 
-can be thrown when a call to `basic_regex::imbue` tries to open a message 
-catalogue that doesn't exist, or when a call to [regex_search] or [regex_match] 
-results in an "everlasting" search, or when a call to `RegEx::GrepFiles` or 
-`RegEx::FindFiles` tries to open a file that cannot be opened, finally 
-`std::bad_alloc` can be thrown by just about any of the functions in this library.
-
-[*Q.] Why can't I use the "convenience" versions of regex_match / 
-regex_search / regex_grep / regex_format / regex_merge?
-
-[*A.] These versions may or may not be available depending upon the 
-capabilities of your compiler, the rules determining the format of 
-these functions are quite complex - and only the versions visible to 
-a standard compliant compiler are given in the help. To find out 
-what your compiler supports, run <boost/regex.hpp> through your 
-C++ pre-processor, and search the output file for the function 
-that you are interested in.  Note however, that very few current
-compilers still have problems with these overloaded functions.

-[section:boost_format_syntax Boost-Extended Format String Syntax]
-
-Boost-Extended format strings treat all characters as literals except for 
-'$', '\\', '(', ')', '?', and ':'.
-
-[h4 Grouping]
-
-The characters '(' and ')' perform lexical grouping, so use \\( and \\) if you 
-want a to output literal parenthesis.
-
-[h4 Conditionals]
-
-The character '?' begins a conditional expression, the general form is:
-
-?Ntrue-expression:false-expression
-
-where N is decimal digit.
-
-If sub-expression N was matched, then true-expression is evaluated and sent to 
-output, otherwise false-expression is evaluated and sent to output.
-
-You will normally need to surround a conditional-expression with parenthesis in 
-order to prevent ambiguities.
-
-For example, the format string "(?1foo:bar)" will replace each match found with "foo" if
-the sub-expression $1 was matched, and with "bar" otherwise.
-
-For sub-expressions with an index greater than 9, or for access to named sub-expressions use:
-
-?{INDEX}true-expression:false-expression
-
-or
-
-?{NAME}true-expression:false-expression
-
-
-[h4 Placeholder Sequences]
-
-Placeholder sequences specify that some part of what matched the regular expression 
-should be sent to output as follows:
-
-[table

-[[$&][Outputs what matched the whole expression.]]
-[[$MATCH][As $&]]
-[[${^MATCH}][As $&]]

-Format strings are used by the algorithm [regex_replace] and by 
-[match_results_format], and are used to transform one string into another.
-
-There are three kind of format string: [sed_format], [perl_format] and [boost_extended_format].
-
-Alternatively, when the flag `format_literal` is passed to one of these functions, 
-then the format string is treated as a string literal, and is copied unchanged 
-to the output.

-
-There are two main headers used by this library: `<boost/regex.hpp>` 
-provides full access to the main template library, while `<boost/cregex.hpp>` 
-provides access to the (deprecated) high level class RegEx, and the 
-POSIX API functions.
-
-There is also a header containing only forward declarations 
-`<boost/regex_fwd.hpp>` for use when an interface is dependent upon 
-[basic_regex], but otherwise does not need the full definitions.

-
-[h4 Boost 1.40]
-
-* Added support for many Perl 5.10 syntax elements including named
-sub-expressions, branch resets and recursive regular expressions.
-
-[h4 Boost 1.38]
-
-* [*Breaking change]: empty expressions, and empty alternatives are now
-allowed when using the Perl regular expression syntax.  This change has
-been added for Perl compatibility, when the new [syntax_option_type]
-['no_empty_expressions] is set then the old behaviour is preserved and
-empty expressions are prohibited.  This is issue
-[@https://svn.boost.org/trac/boost/ticket/1081 #1081].
-* Added support for Perl style ${n} expressions in format strings
-(issue [@https://svn.boost.org/trac/boost/ticket/2556 #2556]).
-* Added support for accessing the location of sub-expressions within the
-regular expression string 
-(issue [@https://svn.boost.org/trac/boost/ticket/2269 #2269]).
-* Fixed compiler compatibility issues 
-[@https://svn.boost.org/trac/boost/ticket/2244 #2244],

-
-
-[h4 Boost 1.34]
-
-* Fix for non-greedy repeats and partial matches not working correctly in some cases.
-* Fix for non-greedy repeats on VC++ not working in some cases (bug report 1515830).
-* Changed match_results::position() to return a valid result when *this represents a partial match.
-* Fixed the grep and egrep options so that the newline character gets treated the same as |.
-
-[h4 Boost 1.33.1]
-
-* Fixed broken makefiles.
-* Fixed configuration setup to allow building with VC7.1 - STLport-4.6.2 when using /Zc:wchar_t.
-* Moved declarations class-inline in static_mutex.hpp so that SGI Irix compiler can cope.
-* Added needed standard library #includes to fileiter.hpp, regex_workaround.hpp and cpp_regex_traits.hpp.
-* Fixed a bug where non-greedy repeats could in certain strange circumstances repeat more times than their maximum value.
-* Fixed the value returned by basic_regex<>::empty() from a default constructed object.
-* Changed the definition of regex_error to make it backwards compatible with Boost-1.32.0.
-* Disabled external templates for Intel C++ 8.0 and earlier - otherwise unresolved references can occur.
-* Rewritten extern template code for gcc so that only specific member functions are exported: otherwise strange unresolved references can occur when linking and mixing debug and non-debug code.
-* Initialise all the data members of the unicode_iterators: this keeps gcc from issuing needless warnings.
-* Ported the ICU integration code to VC6 and VC7.
-* Ensured code is STLport debug mode clean.
-* Fixed lookbehind assertions so that fixed length repeats are permitted, and so that regex iteration allows lookbehind to look back before the current search range (into the last match).
-* Fixed strange bug with non-greedy repeats inside forward lookahead assertions.
-* Enabled negated character classes inside character sets.
-* Fixed regression so that [a-z-] is a valid expression again.
-* Fixed bug that allowed some invalid expressions to be accepted.
-
-[h4 Boost 1.33.0]
-
-* Completely rewritten expression parsing code, and traits class support; now conforms to the standardization proposal.
-* Breaking Change: The syntax options that can be passed to basic_regex constructors have been rationalized.  The default option (perl) now has a value of zero, and it is now clearly documented which options apply to which regular expression syntax styles (perl, POSIX-extended, POSIX-basic etc).  Some of the more esoteric options have now been removed, so there is the possibility that existing code may fail to compile: however equivalent functionality should still be available.
-* Breaking Change: POSIX-extended and POSIX-basic regular expressions now enforce the letter of the POSIX standard much more closely than before.
-* Added support for (?imsx-imsx) constructs.
-* Added support for lookbehind expressions (?<=positive-lookbehind) and (?<!negative-lookbehind).
-* Added support for conditional expressions (?(assertion)true-expression|false-expression).
-* Added MFC/ATL string wrappers.
-* Added Unicode support; based on ICU.
-* Changed newline support to recognise \\f as a line separator (all character types), and \\x85 as a line separator for wide characters / Unicode only.
-* Added a new format flag format_literal that treats the replace string as a literal, rather than a Perl or Sed style format string.
-* Errors are now reported by throwing exceptions of type regex_error. The types used previously - bad_expression and bad_pattern - are now just typedefs for regex_error. Type regex_error has a couple of new members: code() to report an error code rather than a string, and position() to report where in the expression the error occurred.
-
-[h4 Boost 1.32.1]
-
-* Fixed bug in partial matches of bounded repeats of '.'.
-
-[h4 Boost 1.31.0]
-
-* Completely rewritten pattern matching code - it is now up to 10 times faster than before.
-* Reorganized documentation.
-* Deprecated all interfaces that are not part of the regular expression standardization proposal.
-* Added regex_iterator and regex_token_iterator .
-* Added support for Perl style independent sub-expressions.
-* Added non-member operators to the sub_match class, so that you can compare sub_match's with strings, or add them to a string to produce a new string.
-* Added experimental support for extended capture information.
-* Changed the match flags so that they are a distinct type (not an integer), if you try to pass the match flags as an integer rather than match_flag_type to the regex algorithms then you will now get a compiler error.

-        I am indebted to <a href="http://www.cs.princeton.edu/~rs/" target="_top">Robert Sedgewick's
-        "Algorithms in C++"</a> for forcing me to think about algorithms
-        and their performance, and to the folks at boost for forcing me to think,

-        I am also grateful to the manuals supplied with the Henry Spencer, PCRE,

-        - the code however is entirely my own, including any bugs! I can absolutely
-        guarantee that I will not fix any bugs I don't know about, so if you have
-        any comments or spot any bugs, please get in touch.

-        the regular expression \d+ to Boost.Regex, you need to embed "\d+"

-      </p>
-<p>
-        <span class="bold"><strong>A.</strong></span> The algorithm regex_match only succeeds
-        if the expression matches <span class="bold"><strong>all</strong></span> of the text,
-        if you want to <span class="bold"><strong>find</strong></span> a sub-string within
-        the text that matches the expression then use regex_search instead.
-      </p>
-<p>
-        <span class="bold"><strong>Q.</strong></span> Why does using parenthesis in a POSIX
-        regular expression change the result of a match?
-      </p>
-<p>
-        <span class="bold"><strong>A.</strong></span> For POSIX (extended and basic) regular
-        expressions, but not for perl regexes, parentheses don't only mark; they
-        determine what the best match is as well. When the expression is compiled
-        as a POSIX basic or extended regex then Boost.Regex follows the POSIX standard
-        leftmost longest rule for determining what matched. So if there is more than
-        one possible match after considering the whole expression, it looks next
-        at the first sub-expression and then the second sub-expression and so on.
-        So...
-      </p>
-<p>
-        "(0*)([0-9]*)" against "00123" would produce $1 = "00"
-        $2 = "123"
-      </p>
-<p>
-        where as
-      </p>
-<p>
-        "0*([0-9])*" against "00123" would produce $1 = "00123"
-      </p>
-<p>
-        If you think about it, had $1 only matched the "123", this would
-        be "less good" than the match "00123" which is both further
-        to the left and longer. If you want $1 to match only the "123"
-        part, then you need to use something like:
-      </p>
-<p>
-        "0*([1-9][0-9]*)"
-      </p>
-<p>
-        as the expression.
-      </p>
-<p>
-        <span class="bold"><strong>Q.</strong></span> Why don't character ranges work properly
-        (POSIX mode only)?
-      </p>
-<p>
-        <span class="bold"><strong>A.</strong></span> The POSIX standard specifies that character
-        range expressions are locale sensitive - so for example the expression [A-Z]
-        will match any collating element that collates between 'A' and 'Z'. That
-        means that for most locales other than "C" or "POSIX",
-        [A-Z] would match the single character 't' for example, which is not what
-        most people expect - or at least not what most people have come to expect
-        from regular expression engines. For this reason, the default behaviour of
-        Boost.Regex (perl mode) is to turn locale sensitive collation off by not
-        setting the <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">collate</span></code>
-        compile time flag. However if you set a non-default compile time flag - for
-        example <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">extended</span></code> or <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">basic</span></code>,
-        then locale dependent collation will be enabled, this also applies to the
-        POSIX API functions which use either <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">extended</span></code>
-        or <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">basic</span></code> internally. [Note - when <code class="computeroutput"><span class="identifier">regex_constants</span><span class="special">::</span><span class="identifier">nocollate</span></code> in effect, the library behaves
-        "as if" the LC_COLLATE locale category were always "C",
-        regardless of what its actually set to - end note].
-      </p>
-<p>
-        <span class="bold"><strong>Q.</strong></span> Why are there no throw specifications
-        on any of the functions? What exceptions can the library throw?
-      </p>
-<p>
-        <span class="bold"><strong>A.</strong></span> Not all compilers support (or honor)
-        throw specifications, others support them but with reduced efficiency. Throw
-        specifications may be added at a later date as compilers begin to handle
-        this better. The library should throw only three types of exception: [boost::regex_error]
-        can be thrown by <a class="link" href="../ref/basic_regex.html" title="basic_regex"><code class="computeroutput"><span class="identifier">basic_regex</span></code></a> when compiling a regular
-        expression, <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">runtime_error</span></code> can be thrown when a call
-        to <code class="computeroutput"><span class="identifier">basic_regex</span><span class="special">::</span><span class="identifier">imbue</span></code> tries to open a message catalogue
-        that doesn't exist, or when a call to <a class="link" href="../ref/regex_search.html" title="regex_search"><code class="computeroutput"><span class="identifier">regex_search</span></code></a> or <a class="link" href="../ref/regex_match.html" title="regex_match"><code class="computeroutput"><span class="identifier">regex_match</span></code></a> results in an "everlasting"
-        search, or when a call to <code class="computeroutput"><span class="identifier">RegEx</span><span class="special">::</span><span class="identifier">GrepFiles</span></code>
-        or <code class="computeroutput"><span class="identifier">RegEx</span><span class="special">::</span><span class="identifier">FindFiles</span></code> tries to open a file that cannot
-        be opened, finally <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">bad_alloc</span></code> can be thrown by just about any
-        of the functions in this library.
-      </p>
-<p>
-        <span class="bold"><strong>Q.</strong></span> Why can't I use the "convenience"
-        versions of regex_match / regex_search / regex_grep / regex_format / regex_merge?
-      </p>
-<p>
-        <span class="bold"><strong>A.</strong></span> These versions may or may not be available
-        depending upon the capabilities of your compiler, the rules determining the
-        format of these functions are quite complex - and only the versions visible
-        to a standard compliant compiler are given in the help. To find out what
-        your compiler supports, run &lt;boost/regex.hpp&gt; through your C++ pre-processor,
-        and search the output file for the function that you are interested in. Note
-        however, that very few current compilers still have problems with these overloaded
-        functions.

-        The performance of Boost.Regex in both recursive and non-recursive modes

-        If you are using Microsoft or Borland C++ and link to a dll version of the
-        run time library, then you can choose to also link to a dll version of Boost.Regex
-        by defining the symbol BOOST_REGEX_DYN_LINK when you compile your code. While
-        these dll's are redistributable, there are no "standard" versions,
-        so when installing on the users PC, you should place these in a directory
-        private to your application, and not in the PC's directory path. Note that
-        if you link to a static version of your run time library, then you will also
-        link to a static version of Boost.Regex and no dll's will need to be distributed.
-        The possible Boost.Regex dll and library names are computed according to
-        the formula given in <a href="../../../../../../more/getting_started.html" target="_top">the
-        getting started guide</a>.
-      </p>
-<p>
-        Note: you can disable automatic library selection by defining the symbol
-        BOOST_REGEX_NO_LIB when compiling, this is useful if you want to build Boost.Regex
-        yourself in your IDE, or if you need to debug Boost.Regex.

-        In addition the following features behave slightly differently from Perl:

-        Character equivalence classes ( [[=a=]] etc) are probably buggy except on

-        The Boost.Regex library is thread safe when Boost is: you can verify that

-        is defined: this macro is set automatically by the config system when threading
-        support is turned on in your compiler.

-        and its typedefs regex and wregex are thread safe, in that compiled regular
-        expressions can safely be shared between threads. The matching algorithms
-        <a class="link" href="../ref/regex_match.html" title="regex_match"><code class="computeroutput"><span class="identifier">regex_match</span></code></a>,
-        <a class="link" href="../ref/regex_search.html" title="regex_search"><code class="computeroutput"><span class="identifier">regex_search</span></code></a>,
-        and <a class="link" href="../ref/regex_replace.html" title="regex_replace"><code class="computeroutput"><span class="identifier">regex_replace</span></code></a>
-        are all re-entrant and thread safe. Class <a class="link" href="../ref/match_results.html" title="match_results"><code class="computeroutput"><span class="identifier">match_results</span></code></a> is now thread safe,
-        in that the results of a match can be safely copied from one thread to another
-        (for example one thread may find matches and push <a class="link" href="../ref/match_results.html" title="match_results"><code class="computeroutput"><span class="identifier">match_results</span></code></a> instances onto a queue,
-        while another thread pops them off the other end), otherwise use a separate
-        instance of <a class="link" href="../ref/match_results.html" title="match_results"><code class="computeroutput"><span class="identifier">match_results</span></code></a>
-        per thread.

-<p>
-        The <a class="link" href="../ref/posix.html" title="POSIX Compatible C API's">POSIX API functions</a> are
-        all re-entrant and thread safe, regular expressions compiled with regcomp
-        can also be shared between threads.

-<p>
-        The <a class="link" href="../ref/deprecated/old_regex.html" title="High Level Class RegEx (Deprecated)">class RegEx</a>
-        is only thread safe if each thread gets its own RegEx instance (apartment
-        threading) - this is a consequence of RegEx handling both compiling and matching
-        regular expressions.
-      </p>
-<p>
-        Finally note that changing the global locale invalidates all compiled regular
-        expressions, therefore calling <code class="computeroutput"><span class="identifier">set_locale</span></code>
-        from one thread while another uses regular expressions will produce unpredictable
-        results.
-      </p>

-<p>
-      Captures are the iterator ranges that are "captured" by marked sub-expressions
-      as a regular expression gets matched. Each marked sub-expression can result
-      in more than one capture, if it is matched more than once. This document explains
-      how captures and marked sub-expressions in Boost.Regex are represented and
-      accessed.

-    </h5>
-<p>
-      Every time a Perl regular expression contains a parenthesis group <code class="computeroutput"><span class="special">()</span></code>, it spits out an extra field, known as a
-      marked sub-expression, for example the expression:
-    </p>
-<pre class="programlisting">(\w+)\W+(\w+)</pre>
-<p>
-      Has two marked sub-expressions (known as $1 and $2 respectively), in addition
-      the complete match is known as $&amp;, everything before the first match as
-      $`, and everything after the match as $'. So if the above expression is searched
-      for within <code class="computeroutput"><span class="string">"@abc def--"</span></code>,

-      In Boost.Regex each sub-expression match is represented by a <a class="link" href="ref/sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a> object, this is basically
-      just a pair of iterators denoting the start and end position of the sub-expression
-      match, but there are some additional operators provided so that objects of
-      type <a class="link" href="ref/sub_match.html" title="sub_match"><code class="computeroutput"><span class="identifier">sub_match</span></code></a>
-      behave a lot like a <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">basic_string</span></code>: for example they are implicitly
-      convertible to a <code class="computeroutput"><span class="identifier">basic_string</span></code>,
-      they can be compared to a string, added to a string, or streamed out to an
-      output stream.

-      Sub-Expressions</a>
-    </h5>
-<p>
-      When a regular expression match is found there is no need for all of the marked
-      sub-expressions to have participated in the match, for example the expression:
-    </p>
-<pre class="programlisting">(abc)|(def)</pre>
-<p>
-      can match either $1 or $2, but never both at the same time. In Boost.Regex
-      you can determine which sub-expressions matched by accessing the <code class="computeroutput"><span class="identifier">sub_match</span><span class="special">::</span><span class="identifier">matched</span></code> data member.
-    </p>
-<h5>
-<a name="boost_regex.captures.h2"></a>
-      <span class="phrase"><a name="boost_regex.captures.repeated_captures"></a></span><a class="link" href="captures.html#boost_regex.captures.repeated_captures">Repeated
-      Captures</a>
-    </h5>
-<p>
-      When a marked sub-expression is repeated, then the sub-expression gets "captured"
-      multiple times, however normally only the final capture is available, for example
-      if
-    </p>
-<pre class="programlisting">(?:(\w+)\W+)+</pre>
-<p>
-      is matched against
-    </p>
-<pre class="programlisting">one fine day</pre>
-<p>
-      Then $1 will contain the string "day", and all the previous captures
-      will have been forgotten.
-    </p>
-<p>
-      However, Boost.Regex has an experimental feature that allows all the capture
-      information to be retained - this is accessed either via the <code class="computeroutput"><span class="identifier">match_results</span><span class="special">::</span><span class="identifier">captures</span></code> member function or the <code class="computeroutput"><span class="identifier">sub_match</span><span class="special">::</span><span class="identifier">captures</span></code> member function. These functions
-      return a container that contains a sequence of all the captures obtained during
-      the regular expression matching. The following example program shows how this
-      information may be used:
