By default, packages fully using GNU
are installed in such a way as to allow translation of
messages. At configuration time, those packages should
automatically detect whether the underlying host system already provides
gettext functions. If not,
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
use the included GNU
while ‘./configure --disable-nls’
produces programs totally unable to translate messages.
Internationalized packages have usually many ll.po
translations are disabled, all those available are installed together
with the package. However, the environment variable
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.
