wxFileConfig otherwise.

-\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
one (especially because creating a wxFileConfig object might be a time
consuming operation). In this case, you may create this global config object
in the very start of the program and {\it Set()} it as the default. Then, from
-anywhere in your program, you may access it using the {\it Get()} function. Of
-course, you should delete it on the program termination (otherwise, not only a
-memory leak will result, but even more importantly the changes won't be
-written back!).
+anywhere in your program, you may access it using the {\it Get()} function.
+Note that you must delete this object (usually in \helpref{wxApp::OnExit}{wxapponexit})
+in order to avoid memory leaks, wxWindows won't do it automatically.
As it happens, you may even further simplify the procedure described above:
you may forget about calling {\it Set()}. When {\it Get()} is called and there
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.

+As explained in \helpref{config overview}{wxconfigoverview}, the config classes
support a file system-like hierarchy of keys (files) and groups (directories).
As in the file system case, to specify a key in the config class you must use
a path to it. Config classes also support the notion of the current group,
which makes it possible to use the relative paths. To clarify all this, here

no vendor name is wanted, if this is optional for the current config class.

+\docparam{style}{Can be one of wxCONFIG\_USE\_LOCAL\_FILE and
+wxCONFIG\_USE\_GLOBAL\_FILE. The style interpretation depends on the config

+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
+to the style. For wxFileConfig you can also add wxCONFIG\_USE\_RELATIVE\_PATH
+by logically or'ing it to either of the \_FILE options to tell wxFileConfig to
+use relative instead of absolute paths. For wxFileConfig, you can also
+add wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS which will turn off character
+escaping for the values of entries stored in the config file: for example
+a {\it foo} key with some backslash characters will be stored as {\tt foo=C:$\backslash$mydir} instead
+of the usual storage of {\tt foo=C:$\backslash\backslash$mydir}.
+
+The wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS style can be helpful if your config
+file must be read or written to by a non-wxWindows program (which might not
+understand the escape characters). Note, however, that if
+wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS style is used, it is is now
+your application's responsibility to ensure that there is no newline or
+other illegal characters in a value, before writing that value to the file.}

+SetUmask() allows to set the mode to be used for the config file creation.
+For example, to create a config file which is not readable by other users
+(useful if it stores some sensitive information, such as passwords), you
+should do {\tt SetUmask(0077)}.
