wxConfigBase class defines the basic interface of all config classes. It can
not be used by itself (it's an abstract base class) and you'll always use one
-of its derivations: \helpref{wxIniConfig}{wxiniconfig},
-\helpref{wxFileConfig}{wxfileconfig}, \helpref{wxRegConfig}{wxregconfig} or
-any other.
+of its derivations: wxIniConfig, wxFileConfig, wxRegConfig or any other.
However, usually you don't even need to know the precise nature of the class
you're working with but you would just use the wxConfigBase methods. This
See \helpref{config overview}{wxconfigoverview} for the descriptions of all
features of this class.
+It is highly recommended to use static functions {\it Get()} and/or {\it Set()},
+so please have a \helpref{look at them.}{wxconfigstaticfunctions}

-\membersection{Static functions}
+\membersection{Static functions}\label{wxconfigstaticfunctions}
These functions deal with the "default" config object. Although its usage is
not at all mandatory it may be convenient to use a global config object
is no current object, it will create one using {\it Create()} function. To
disable this behaviour {\it DontCreateOnDemand()} is provided.
+{\bf Note:} You should use either {\it Set()} or {\it Get()} because wxWindows
+library itself would take advantage of it and could save various information
+in it. For example \helpref{wxFontMapper}{wxfontmapper} or Unix version
+of \helpref{wxFileDialog}{wxfiledialog} have ability to use wxConfig class.

+\membersection{Rename entries/groups}
+
+The functions in this section allow to rename entries or subgroups of the
+current group. They will return FALSE on error. typically because either the
+entry/group with the original name doesn't exist, because the entry/group with
+the new name already exists or because the function is not supported in this
+wxConfig implementation.

\membersection{Delete entries/groups}
The functions in this section delete entries and/or groups of entries from the
a local or global config file is created or used. If the flag is present but
the parameter is empty, the parameter will be set to a default. If the
parameter is present but the style flag not, the relevant flag will be added

+use relative instead of absolute paths. }

\membersection{wxConfigBase::Get}\label{wxconfigbaseget}

\membersection{wxConfigBase::GetAppName}\label{wxconfigbasegetappname}
Returns the application name.
+\membersection{wxConfigBase::GetEntryType}\label{wxconfigbasegetentrytype}
+
+\constfunc{enum wxConfigBase::EntryType}{GetEntryType}{\param{const wxString\& }{name}}
+
+Returns the type of the given entry or {\it Unknown} if the entry doesn't
+exist. This function should be used to decide which version of Read() should
+be used because some of wxConfig implementations will complain about type
+mismatch otherwise: e.g., an attempt to read a string value from an integer
+key with wxRegConfig will fail.
+
+The result is an element of enum EntryType:

+ Unknown,
+ String,
+ Boolean,
+ Integer,
+ Float
+ };

+
+\func{bool}{RenameEntry}{\param{const wxString\& }{ oldName}, \param{const wxString\& }{ newName}}
+
+Renames an entry in the current group. The entries names (both the old and
