overview = """\

The <b>wx.MimeTypesManager</b> class allows the application to retrieve the 
information about all known MIME types from a system-specific location and the 
filename extensions to the MIME types and vice versa. After initialization the 
methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b> 
may be called: they will return a <b>wx.FileType</b> object which may be further 
queried for file description, icon and other attributes.

A global instance of <b>wx.MimeTypesManager</b> is always available as
<b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead 
of creating your own because gathering MIME information may take quite a long 
on Unix systems.

This demo shows how to use wx.TheMimeTypesManager to list all known MIME types
and retrieve that information as a wx.FileType from either an extension or
MIME type.

For further information please consult the wxWindows documentation for
<b>wx.MimeTypesManager</b> and <b>wx.FileType</b>.

cc6eca35 RD	319	The <b>wx.MimeTypesManager</b> class allows the application to retrieve the
	320	information about all known MIME types from a system-specific location and the
	321	filename extensions to the MIME types and vice versa. After initialization the
	322	methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b>
	323	may be called: they will return a <b>wx.FileType</b> object which may be further
	324	queried for file description, icon and other attributes.
b37c7e1d	325
cc6eca35 RD	326	A global instance of <b>wx.MimeTypesManager</b> is always available as
	327	<b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead
	328	of creating your own because gathering MIME information may take quite a long
	329	on Unix systems.

cc6eca35 RD	331	This demo shows how to use wx.TheMimeTypesManager to list all known MIME types
	332	and retrieve that information as a wx.FileType from either an extension or
