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

+\begin{verbatim}
+wxMimeTypesManager *wxTheMimeTypesManager;

+It is recommended to use this instance instead of creating your own because
+gathering MIME information may take quite a long time on Unix systems.

These functions are the heart of this class: they allow to find a \helpref{file type}{wxfiletype} object
from either file extension or MIME type.
If the function is successful, it returns a pointer to the wxFileType object

\membersection{wxMimeTypesManager::GetFileTypeFromExtension}\label{wxmimetypesmanagergetfiletypefromextension}

Gather information about the files with given extension and return the

+corresponding \helpref{wxFileType}{wxfiletype} object or \NULL if the extension
is unknown.
+The \arg{extension} parameter may have, or not, the leading dot, if it has it,

is unknown.

+\membersection{wxMimeTypesManager::IsOfType}\label{wxmimetypesmanagerisoftype}

+\func{bool}{IsOfType}{\param{const wxString\&}{ mimeType}, \param{const wxString\&}{ wildcard}}

+This function returns true if either the given {\it mimeType} is exactly the
+same as {\it wildcard} or if it has the same category and the subtype of
+{\it wildcard} is '*'. Note that the '*' wildcard is not allowed in
+{\it mimeType} itself.

-\func{void}{ReadMailcap}{\param{const wxString\&}{ filename}}

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.

\membersection{wxMimeTypesManager::ReadMimeTypes}\label{wxmimetypesmanagerreadmimetypes}

Load additional file containing information about MIME types and associated
information in mime.types file format. See metamail(1) and mailcap(5) for more
information.
+The return value is true if there were no errors in the file or false
+otherwise.
