+If GNOME or KDE desktop environment is installed, then wxMimeTypesManager
+gathers MIME information from respective files (e.g. .kdelnk files under KDE).

NB: Currently, wxMimeTypesManager is limited to reading MIME type information
but it will support modifying it as well in the future versions.

+Global instance of wxMimeTypesManager is always available. It is defined
+as follows:
-#include <wx/mimetype.h>
+\begin{verbatim}
+wxMimeTypesManager *wxTheMimeTypesManager;
+\end{verbatim}
+
+It is recommended to use this instance instead of creating your own because
+gathering MIME information may take quite a long on Unix systems.

+All of these functions are static (i.e. don't need a wxMimeTypesManager object
+to call them) and provide some useful operations for string representations of
+MIME types. Their usage is recommended instead of directly working with MIME
+types using wxString functions.

-\func{wxFileType *}{GetFileTypeFromExtension}{\param{const wxString \&}{extension}}

Gather information about the files with given extension and return the
corresponding \helpref{wxFileType}{wxfiletype} object or NULL if the extension
is unknown.

Load additional file containing information about MIME types and associated
information in mailcap format. See metamail(1) and mailcap(5) for more
information.
+{\it fallback} parameter may be used to load additional mailcap files without
+overriding the settings found in the standard files: normally, entries from
+files loaded with ReadMailcap will override the entries from files loaded
+previously (and the standard ones are loaded in the very beginning), but this
+will not happen if this parameter is set to true (default is false).

+The return value is true if there were no errors in the file or false
+otherwise.

Load additional file containing information about MIME types and associated

information.

+The return value is true if there were no errors in the file or false
+otherwise.
