wxLocale class encapsulates all language-dependent settings and is a
generalization of the C locale concept.
-In wxWindows this class manages message catalogs which contain the translations
+In wxWidgets this class manages message catalogs which contain the translations
of the strings used to the current language.
-\perlnote{In wxPerl the {\tt Wx} module exports a '\_' function

+\perlnote{In wxPerl you can't use the '\_' function name, so

+{\tt gettext\_noop} under any given name.

\begin{verbatim}

+
Retrieves the translation for a string in all loaded domains unless the szDomain
parameter is specified (and then only this catalog/domain is searched).
(in this case an error message is generated the first time
a string is not found; use \helpref{wxLogNull}{wxlogoverview} to suppress it).
+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{szOrigString}
+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{szOrigString2} parameter is the plural form (in English).
+The parameter \arg{n} is used to determine the plural form. If no
+message catalog is found \arg{szOrigString} is returned if `n == 1',
+otherwise \arg{szOrigString2}.
+See \urlref{GNU gettext manual}{http://www.gnu.org/manual/gettext/html\_chapter/gettext\_10.html\#SEC150} for additional information on plural forms handling.
