\membersection{Construction}\label{wxcmdlineparserconstruction}
Before \helpref{Parse}{wxcmdlineparserparse} can be called, the command line

{\tt AddXXX()} functions above might be preferable.

\membersection{Customization}\label{wxcmdlineparsercustomization}
wxCmdLineParser has several global options which may be changed by the
application-specific text before the explanation given by
\helpref{Usage}{wxcmdlineparserusage} function.

\membersection{Parsing command line}\label{wxcmdlineparserparsing}
After the command line description was constructed and the desired options were
In the latter case, the appropriate error message and usage information are
logged by wxCmdLineParser itself using the standard wxWidgets logging functions.

+
Constructor specifies the command line to parse. This is the traditional
(Unix) command line format. The parameters {\it argc} and {\it argv} have the
same meaning as for {\tt main()} function.
+The second overloaded constructor is only available in Unicode build. The
+first one is available in both ANSI and Unicode modes because under some
+platforms the command line arguments are passed as ASCII strings even to
+Unicode programs.
+

\func{static wxArrayString}{ConvertStringToArgs}{\param{const wxChar }{*cmdline}}
separated by whitespace. The quotes can be used in the input string to quote
the white space and the back slashes can be used to quote the quotes.
