which are well handled by wxTextFile.
The typical things you may do with wxTextFile in order are:
\item Add/remove lines to the file: \helpref{AddLine}{wxtextfileaddline} and
\helpref{InsertLine}{wxtextfileinsertline} add new lines while
\helpref{RemoveLine}{wxtextfileremoveline} deletes the existing ones.
+\helpref{Clear}{wxtextfileclear} resets the file to empty.
\item Save your changes: notice that the changes you make to the file will {\bf
not} be saved automatically; calling \helpref{Close}{wxtextfileclose} or doing
nothing discards them! To save the changes you must explicitly call
<wx/textfile.h>

The following constants identify the line termination type:
\constfunc{bool}{Exists}{\void}
-Return TRUE if file exists - the name of the file should have been specified
+Return true if file exists - the name of the file should have been specified
in the constructor before calling Exists().

\constfunc{bool}{IsOpened}{\void}
-Returns TRUE if the file is currently opened.
+Returns true if the file is currently opened.
\membersection{wxTextFile::GetLineCount}\label{wxtextfilegetlinecount}
\constfunc{bool}{Eof}{\void}
-Returns TRUE if the current line is the last one.
+Returns true if the current line is the last one.

Open() opens the file with the given name or the name which was given in the
\helpref{constructor}{wxtextfilector} and also loads file in memory on
success. It will fail if the file does not exist,
\helpref{Create}{wxtextfilecreate} should be used in this case.

Change the file on disk. The {\it typeNew} parameter allows you to change the
file format (default argument means "don't change type") and may be used to
convert, for example, DOS files to Unix.
