 \section{\class{wxString}}\label{wxstring}
 
+wxString is a class representing a character string. Please see the 
+\helpref{wxString overview}{wxstringoverview} for more information about it. As explained
+there, wxString implements about 90\% of methods of the std::string class (iterators
+are not supported, nor all methods which use them).
+These standard functions are not documented in this manual so please see the STL documentation.
+The behaviour of all these functions is identical to the behaviour described
+there.

+
+\membersection{Constructors and assignment operators}
+
+A strign may be constructed either from a C string, (some number of copies of)
+a single character or a wide (UNICODE) string. For all constructors (except the
+default which creates an empty string) there is also a corresponding assignment
+operator.
+
+\helpref{wxString}{wxstringconstruct}\\
+\helpref{operator $=$}{wxstringoperatorassign}\\
+\helpref{\destruct{wxString}}{wxstringdestruct}
+
+\membersection{String length}
+
+These functions return the string length and check whether the string is empty
+or empty it.
+
+\helpref{Len}{wxstringlen}\\
+\helpref{IsEmpty}{wxstringisempty}\\
+\helpref{operator!}{wxstringoperatornot}\\
+\helpref{Empty}{wxstringempty}\\
+\helpref{Clear}{wxstringclear}
+
+\membersection{Character access}
+
+Many functions in this section take a character index in the string. As with C
+strings and/or arrays, the indices start from $0$, so the first character of a
+string is string[$0$]. Attempt to access a character beyond the end of the
+string (which may be even $0$ if the string is empty) will provocate an assert
+failure in \helpref{debug build}{debuggingoverview}, but no checks are done in
+release builds.
+
+This section also contains both implicit and explicit conversions to C style
+strings. Although implicit conversion is quite convenient, it is advised to use
+explicit \helpref{c\_str()}{wxstringcstr} method for the sake of clarity. Also
+see \helpref{overview}{wxstringadvices} for the cases where it is necessary to
+use it.
+
+\helpref{GetChar}{wxstringgetchar}\\
+\helpref{GetWritableChar}{wxstringgetwritablechar}\\
+\helpref{SetChar}{wxstringsetchar}\\
+\helpref{Last}{wxstringlast}\\
+\helpref{operator []}{wxstringoperatorbracket}\\
+\helpref{c\_str}{wxstringcstr}\\
+\helpref{operator const char*}{wxstringoperatorconstcharpt}
+
+\membersection{Concatenation}
+
+Anything may be concatenated (appended to) with a string. However, you can't
+append something to a C string (including literal constants), so to do this it
+should be converted to a wxString first.
+
+\helpref{operator \cinsert}{wxstringoperatorout}\\
+\helpref{operator $+=$}{wxstringplusequal}\\
+\helpref{operator $+$}{wxstringoperatorplus}\\
+\helpref{Append}{wxstringappend}\\
+\helpref{Prepend}{wxstringprepend}
+
+\membersection{Comparison}
+
+The default comparison function \helpref{Cmp}{wxstringcmp} is case-sensitive and
+so is the default version of \helpref{IsSameAs}{wxstringissameas}. For case
+insensitive comparisons you should use \helpref{CmpNoCase}{wxstringcmpnocase} or
+give a second parameter to IsSameAs. This last function is may be more
+convenient if only equality of the strings matters because it returns a boolean
+true value if the strings are the same and not 0 (which is usually FALSE in C)
+as {\tt Cmp()} does.
+
+\helpref{Matches}{wxstringmatches} is a poor man's regular expression matcher:
+it only understands '*' and '?' metacharacters in the sense of DOS command line
+interpreter.
+
+\helpref{StartsWith}{wxstringstartswith} is helpful when parsing a line of
+text which should start with some predefined prefix and is more efficient than
+doing direct string comparaison as you would also have to precalculate the
+length of the prefix then.
+
+\helpref{Cmp}{wxstringcmp}\\
+\helpref{CmpNoCase}{wxstringcmpnocase}\\
+\helpref{IsSameAs}{wxstringissameas}\\
+\helpref{Matches}{wxstringmatches}\\
+\helpref{StartsWith}{wxstringstartswith}
+
+\membersection{Substring extraction}
+
+These functions allow to extract substring from this string. All of them don't
+modify the original string and return a new string containing the extracted
+substring.
+
+\helpref{Mid}{wxstringmid}\\
+\helpref{operator()}{wxstringoperatorparenth}\\
+\helpref{Left}{wxstringleft}\\
+\helpref{Right}{wxstringright}\\
+\helpref{BeforeFirst}{wxstringbeforefirst}\\
+\helpref{BeforeLast}{wxstringbeforelast}\\
+\helpref{AfterFirst}{wxstringafterfirst}\\
+\helpref{AfterLast}{wxstringafterlast}\\
+\helpref{StartsWith}{wxstringstartswith}
+
+\membersection{Case conversion}
+
+The MakeXXX() variants modify the string in place, while the other functions
+return a new string which containts the original text converted to the upper or
+lower case and leave the original string unchanged.
+
+\helpref{MakeUpper}{wxstringmakeupper}\\
+\helpref{Upper}{wxstringupper}\\
+\helpref{MakeLower}{wxstringmakelower}\\
+\helpref{Lower}{wxstringlower}
+
+\membersection{Searching and replacing}
+
+These functions replace the standard {\it strchr()} and {\it strstr()} 
+functions.
+
+\helpref{Find}{wxstringfind}\\
+\helpref{Replace}{wxstringreplace}
+
+\membersection{Conversion to numbers}
+
+The string provides functions for conversion to signed and unsigned integer and
+floating point numbers. All three functions take a pointer to the variable to
+put the numeric value in and return TRUE if the {\bf entire} string could be
+converted to a number.
+
+\helpref{ToLong}{wxstringtolong}\\
+\helpref{ToULong}{wxstringtoulong}\\
+\helpref{ToDouble}{wxstringtodouble}
+
+\membersection{Writing values into the string}
+
+Both formatted versions (\helpref{Printf}{wxstringprintf}) and stream-like
+insertion operators exist (for basic types only). Additionally, the 
+\helpref{Format}{wxstringformat} function allows to use simply append
+formatted value to a string:
+
+\begin{verbatim}
+    // the following 2 snippets are equivalent
+
+    wxString s = "...";
+    s += wxString::Format("%d", n);
+
+    wxString s;
+    s.Printf("...%d", n);
+\end{verbatim}
+
+\helpref{Format}{wxstringformat}\\
+\helpref{FormatV}{wxstringformatv}\\
+\helpref{Printf}{wxstringprintf}\\
+\helpref{PrintfV}{wxstringprintfv}\\
+\helpref{operator \cinsert}{wxstringoperatorout}
+
+\membersection{Memory management}
+
+These are "advanced" functions and they will be needed quite rarily. 
+\helpref{Alloc}{wxstringalloc} and \helpref{Shrink}{wxstringshrink} are only
+interesting for optimization purposes. 
+\helpref{GetWriteBuf}{wxstringgetwritebuf} may be very useful when working with
+some external API which requires the caller to provide a writable buffer, but
+extreme care should be taken when using it: before performing any other
+operation on the string \helpref{UngetWriteBuf}{wxstringungetwritebuf} {\bf
+must} be called!
+
+\helpref{Alloc}{wxstringalloc}\\
+\helpref{Shrink}{wxstringshrink}\\

+functions instead of them (or, even better, std::string compatible variants).
