/** Perl-compatible regular expressions - matches strings against regular expressions.
*
* The Glib::Regex functions implement regular expression pattern matching using
* syntax and semantics similar to Perl regular expression.
*
* Some functions accept a start_position argument, setting it differs from just
* passing over a shortened string and setting REGEX_MATCH_NOTBOL in the case
* of a pattern that begins with any kind of lookbehind assertion. For example,
* consider the pattern "\Biss\B" which finds occurrences of "iss" in the middle
* of words. ("\B" matches only if the current position in the subject is not a
* word boundary.) When applied to the string "Mississipi" from the fourth byte,
* namely "issipi", it does not match, because "\B" is always false at the
* start of the subject, which is deemed to be a word boundary. However, if
* the entire string is passed , but with start_position set to 4, it finds the
* second occurrence of "iss" because it is able to look behind the starting point
* to discover that it is preceded by a letter.
*
* Note that, unless you set the REGEX_RAW flag, all the strings passed to these
* functions must be encoded in UTF-8. The lengths and the positions inside the
* strings are in bytes and not in characters, so, for instance,
* "\xc3\xa0" (i.e. "à") is two bytes long but it is treated as a single
* character. If you set REGEX_RAW the strings can be non-valid UTF-8 strings
* and a byte is treated as a character, so "\xc3\xa0" is two bytes and
* two characters long.
*
* When matching a pattern, "\n" matches only against a "\n" character in the
* string, and "\r" matches only a "\r" character. To match any newline sequence
* use "\R". This particular group matches either the two-character sequence
* CR + LF ("\r\n"), or one of the single characters LF (linefeed, U+000A, "\n"),
* VT (vertical tab, U+000B, "\v"), FF (formfeed, U+000C, "\f"), CR (carriage
* return, U+000D, "\r"), NEL (next line, U+0085), LS (line separator, U+2028),
* or PS (paragraph separator, U+2029).
*
* The behaviour of the dot, circumflex, and dollar metacharacters are affected
* by newline characters, the default is to recognize any newline character (the
* same characters recognized by "\R"). This can be changed with REGEX_NEWLINE_CR,
* REGEX_NEWLINE_LF and REGEX_NEWLINE_CRLF compile options, and with
* REGEX_MATCH_NEWLINE_ANY, REGEX_MATCH_NEWLINE_CR, REGEX_MATCH_NEWLINE_LF
* and REGEX_MATCH_NEWLINE_CRLF match options. These settings are also
* relevant when compiling a pattern if REGEX_EXTENDED is set, and an unescaped
* "#" outside a character class is encountered. This indicates a comment that
* lasts until after the next newline.
*
* Creating and manipulating the same Glib::Regex class from different threads is
* not a problem as Glib::Regex does not modify its internal state between creation and
* destruction, on the other hand Glib::MatchInfo is not threadsafe.
*
* The regular expressions low level functionalities are obtained through the
* excellent PCRE library written by Philip Hazel.
