Magic for Installers
====================
By default, packages fully using GNU `gettext', internally, are
installed in such a way that they to allow translation of messages. At
_configuration_ time, those packages should automatically detect
whether the underlying host system already provides the GNU `gettext'
functions. If not, the GNU `gettext' library should be automatically
prepared and used. Installers may use special options at configuration
time for changing this behavior. The command `./configure
--with-included-gettext' bypasses system `gettext' to use the included
GNU `gettext' instead, while `./configure --disable-nls' produces
programs totally unable to translate messages.
Internationalized packages have usually many `LL.po' files. Unless
translations are disabled, all those available are installed together
with the package. However, the environment variable `LINGUAS' may be
set, prior to configuration, to limit the installed set. `LINGUAS'
should then contain a space separated list of two-letter codes, stating
which languages are allowed.
