This installs the function \function{_} in Python's builtin namespace,
based on \var{domain}, \var{localedir}, and \var{codeset} which are
passed to the function \function{translation()}. The \var{unicode}
flag is passed to the resulting translation object's \method{install}
method.
+For the \var{names} parameter, please see the description of the
+translation object's \method{install} method.
+
As seen below, you usually mark the strings in your application that are
candidates for translation, by wrapping them in a call to the
\function{_()} function, like this:
of your application.

+\begin{methoddesc}[NullTranslations]{install}{\optional{unicode
+ \optional{, names}}}
If the \var{unicode} flag is false, this method installs
\method{self.gettext()} into the built-in namespace, binding it to
\samp{_}. If \var{unicode} is true, it binds \method{self.ugettext()}
instead. By default, \var{unicode} is false.
+If the \var{names} parameter is given, it must be a sequence containing
+the names of functions you want to install in the builtin namespace in
+addition to \function{_()}. Supported names are \code{'gettext'} (bound
+to \method{self.gettext()} or \method{self.ugettext()} according to the
+\var{unicode} flag), \code{'ngettext'} (bound to \method{self.ngettext()}
+or \method{self.ungettext()} according to the \var{unicode} flag),
+\code{'lgettext'} and \code{'lngettext'}.
+
Note that this is only one way, albeit the most convenient way, to
make the \function{_} function available to your application. Because it
affects the entire application globally, and specifically the built-in
This puts \function{_} only in the module's global namespace and so
only affects calls within this module.
