The field {\tt shortName} is the usual, short, name of the switch or the option.
-{\tt longName} is the corresponding long name or NULL if the option has no long
+{\tt longName} is the corresponding long name or empty if the option has no long
name. Both of these fields are unused for the parameters. Both the short and
long option names can contain only letters, digits and the underscores.

\membersection{Construction}\label{wxcmdlineparserconstruction}
Before \helpref{Parse}{wxcmdlineparserparse} can be called, the command line
\helpref{Parse}{wxcmdlineparserparse}.
To specify the command line to parse you may use either one of constructors
-accepting it (\helpref{wxCmdLineParser(argc, argv)}{wxcmdlineparserwxcmdlineparserargc} or
-\helpref{wxCmdLineParser}{wxcmdlineparserwxcmdlineparserdescargc} usually) or,
-if you use \helpref{the default constructor}{wxcmdlineparserwxcmdlineparserdef},
-you can do it later by calling
-\helpref{SetCmdLine}{wxcmdlineparsersetcmdlineargc}.
+accepting it (\tt{wxCmdLineParser(argc, argv)} or \tt{wxCmdLineParser(const wxString&)} usually)
+or, if you use the default constructor, you can do it later by calling
+\helpref{SetCmdLine}{wxcmdlineparsersetcmdline}.
The same holds for command line description: it can be specified either in
-the constructor (\helpref{without command line}{wxcmdlineparserwxcmdlineparserdesc} or
-\helpref{together with it}{wxcmdlineparserwxcmdlineparserdescargc}) or
-constructed later using either \helpref{SetDesc}{wxcmdlineparsersetdesc} or
-combination of \helpref{AddSwitch}{wxcmdlineparseraddswitch},
+the \helpref{constructor}{wxcmdlineparserwxcmdlineparserctor} (with or without
+the command line itself) or constructed later using either
+\helpref{SetDesc}{wxcmdlineparsersetdesc} or combination of
+\helpref{AddSwitch}{wxcmdlineparseraddswitch},
\helpref{AddOption}{wxcmdlineparseraddoption} and
\helpref{AddParam}{wxcmdlineparseraddparam} methods.
Using constructors or \helpref{SetDesc}{wxcmdlineparsersetdesc} uses a (usually
{\tt const static}) table containing the command line description. If you want
-to decide which options to acccept during the run-time, using one of the

{\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

methods.
For a simple switch, you will simply call
-\helpref{Found}{wxcmdlineparserfoundswitch} to determine if the switch was given
+\helpref{Found}{wxcmdlineparserfound} to determine if the switch was given
or not, for an option or a parameter, you will call a version of {\tt Found()}
which also returns the associated value in the provided variable. All
-{\tt Found()} functions return TRUE if the switch or option were found in the
-command line or FALSE if they were not specified.
+{\tt Found()} functions return true if the switch or option were found in the
+command line or false if they were not specified.
