This function returns the translation of string {\it str} in the current
\helpref{locale}{wxlocale}. If the string is not found in any of the loaded
message catalogs (see \helpref{internationalization overview}{internationalization}), the
original string is returned. In debug build, an error message is logged -- this

+for a matching string. As this function
is used very often, an alternative (and also common in Unix world) syntax is
provided: the \helpref{\_()}{underscore} macro is defined to do the same thing
as wxGetTranslation.
The second form is used when retrieving translation of string that has
different singular and plural form in English or different plural forms in some
-other language. It takes two extra arguments: \arg{str}
-parameter must contain the singular form of the string to be converted.
-It is also used as the key for the search in the catalog.
-The \arg{strPlural} parameter is the plural form (in English).

+plural form. If no message catalog is found \arg{str} is returned if `n == 1',
otherwise \arg{strPlural}.

+builds, since the literal strings must be enclosed into
+\helpref{\_T()}{underscoret} or \helpref{wxT}{wxt} macro which makes them
+unrecognised by \texttt{xgettext}, and so they are not extracted to the message
