-// This is a variant of PCRE's pcrecpp.h, originally written at Google.
-// The main changes are the addition of the HitLimit method and
-// compilation as PCRE in namespace re2.
-
-// C++ interface to the pcre regular-expression library.  PCRE supports
-// Perl-style regular expressions (with extensions like \d, \w, \s,
-// ...).
-//
-// -----------------------------------------------------------------------
-// REGEXP SYNTAX:
-//
-// This module uses the pcre library and hence supports its syntax
-// for regular expressions:
-//
-//      http://www.google.com/search?q=pcre
-//
-// The syntax is pretty similar to Perl's.  For those not familiar
-// with Perl's regular expressions, here are some examples of the most
-// commonly used extensions:
-//
-//   "hello (\\w+) world"  -- \w matches a "word" character
-//   "version (\\d+)"      -- \d matches a digit
-//   "hello\\s+world"      -- \s matches any whitespace character
-//   "\\b(\\w+)\\b"        -- \b matches empty string at a word boundary
-//   "(?i)hello"           -- (?i) turns on case-insensitive matching
-//   "/\\*(.*?)\\*/"       -- .*? matches . minimum no. of times possible
-//
-// -----------------------------------------------------------------------
-// MATCHING INTERFACE:
-//
-// The "FullMatch" operation checks that supplied text matches a
-// supplied pattern exactly.
-//
-// Example: successful match
-//    CHECK(PCRE::FullMatch("hello", "h.*o"));
-//
-// Example: unsuccessful match (requires full match):
-//    CHECK(!PCRE::FullMatch("hello", "e"));
-//
-// -----------------------------------------------------------------------
-// UTF-8 AND THE MATCHING INTERFACE:
-//
-// By default, pattern and text are plain text, one byte per character.
-// The UTF8 flag, passed to the constructor, causes both pattern
-// and string to be treated as UTF-8 text, still a byte stream but
-// potentially multiple bytes per character. In practice, the text
-// is likelier to be UTF-8 than the pattern, but the match returned
-// may depend on the UTF8 flag, so always use it when matching
-// UTF8 text.  E.g., "." will match one byte normally but with UTF8
-// set may match up to three bytes of a multi-byte character.
-//
-// Example:
-//    PCRE re(utf8_pattern, PCRE::UTF8);
-//    CHECK(PCRE::FullMatch(utf8_string, re));
-//
-// -----------------------------------------------------------------------
-// MATCHING WITH SUB-STRING EXTRACTION:
-//
-// You can supply extra pointer arguments to extract matched subpieces.
-//
-// Example: extracts "ruby" into "s" and 1234 into "i"
-//    int i;
-//    string s;
-//    CHECK(PCRE::FullMatch("ruby:1234", "(\\w+):(\\d+)", &s, &i));
-//
-// Example: fails because string cannot be stored in integer
-//    CHECK(!PCRE::FullMatch("ruby", "(.*)", &i));
-//
-// Example: fails because there aren't enough sub-patterns:
-//    CHECK(!PCRE::FullMatch("ruby:1234", "\\w+:\\d+", &s));
-//
-// Example: does not try to extract any extra sub-patterns
-//    CHECK(PCRE::FullMatch("ruby:1234", "(\\w+):(\\d+)", &s));
-//
-// Example: does not try to extract into NULL
-//    CHECK(PCRE::FullMatch("ruby:1234", "(\\w+):(\\d+)", NULL, &i));
-//
-// Example: integer overflow causes failure
-//    CHECK(!PCRE::FullMatch("ruby:1234567891234", "\\w+:(\\d+)", &i));
-//
-// -----------------------------------------------------------------------
-// PARTIAL MATCHES
-//
-// You can use the "PartialMatch" operation when you want the pattern
-// to match any substring of the text.
-//
-// Example: simple search for a string:
-//      CHECK(PCRE::PartialMatch("hello", "ell"));
-//
-// Example: find first number in a string
-//      int number;
-//      CHECK(PCRE::PartialMatch("x*100 + 20", "(\\d+)", &number));
-//      CHECK_EQ(number, 100);
-//
-// -----------------------------------------------------------------------
-// PPCRE-COMPILED PCREGULAR EXPPCRESSIONS
-//
-// PCRE makes it easy to use any string as a regular expression, without
-// requiring a separate compilation step.
-//
-// If speed is of the essence, you can create a pre-compiled "PCRE"
-// object from the pattern and use it multiple times.  If you do so,
-// you can typically parse text faster than with sscanf.
-//
-// Example: precompile pattern for faster matching:
-//    PCRE pattern("h.*o");
-//    while (ReadLine(&str)) {
-//      if (PCRE::FullMatch(str, pattern)) ...;
-//    }
-//
-// -----------------------------------------------------------------------
-// SCANNING TEXT INCPCREMENTALLY
-//
-// The "Consume" operation may be useful if you want to repeatedly
-// match regular expressions at the front of a string and skip over
-// them as they match.  This requires use of the "StringPiece" type,
-// which represents a sub-range of a real string.
-//
-// Example: read lines of the form "var = value" from a string.
-//      string contents = ...;          // Fill string somehow
-//      StringPiece input(contents);    // Wrap a StringPiece around it
-//
-//      string var;
-//      int value;
-//      while (PCRE::Consume(&input, "(\\w+) = (\\d+)\n", &var, &value)) {
-//        ...;
-//      }
-//
-// Each successful call to "Consume" will set "var/value", and also
-// advance "input" so it points past the matched text.  Note that if the
-// regular expression matches an empty string, input will advance
-// by 0 bytes.  If the regular expression being used might match
-// an empty string, the loop body must check for this case and either
-// advance the string or break out of the loop.
-//
-// The "FindAndConsume" operation is similar to "Consume" but does not
-// anchor your match at the beginning of the string.  For example, you
-// could extract all words from a string by repeatedly calling
-//     PCRE::FindAndConsume(&input, "(\\w+)", &word)
-//
-// -----------------------------------------------------------------------
-// PARSING HEX/OCTAL/C-RADIX NUMBERS
-//
-// By default, if you pass a pointer to a numeric value, the
-// corresponding text is interpreted as a base-10 number.  You can
-// instead wrap the pointer with a call to one of the operators Hex(),
-// Octal(), or CRadix() to interpret the text in another base.  The
-// CRadix operator interprets C-style "0" (base-8) and "0x" (base-16)
-// prefixes, but defaults to base-10.
-//
-// Example:
-//   int a, b, c, d;
-//   CHECK(PCRE::FullMatch("100 40 0100 0x40", "(.*) (.*) (.*) (.*)",
-//         Octal(&a), Hex(&b), CRadix(&c), CRadix(&d));
-// will leave 64 in a, b, c, and d.
