|
| <p>By default, packages fully using GNU <code>gettext</code>, internally, |
| are installed in such a way as to allow translation of |
| messages. At <em>configuration</em> time, those packages should |
| automatically detect whether the underlying host system already provides |
| the GNU <code>gettext</code> functions. If not, |
| the GNU <code>gettext</code> library should be automatically prepared |
| and used. Installers may use special options at configuration |
| time for changing this behavior. The command ‘<samp>./configure |
| --with-included-gettext</samp>’ bypasses system <code>gettext</code> to |
| use the included GNU <code>gettext</code> instead, |
| while ‘<samp>./configure --disable-nls</samp>’ |
| produces programs totally unable to translate messages. |
| </p> |
| <a name="IDX1154"></a> |
| <p>Internationalized packages have usually many ‘<tt><var>ll</var>.po</tt>’ |
| or ‘<tt><var>ll</var>_<var>CC</var>.po</tt>’ files, where |
| </p> |
| <ul> |
| <li> |
| <var>ll</var> gives an ISO 639 two-letter code identifying the language. |
| For some languages, |
| a two-letter code does not exist, and a three-letter code is used instead. |
| </li><li> |
| The optional <var>CC</var> is an ISO 3166 two-letter code of a country or |
| territory. |
| </li></ul> |
|
|
| <p>Unless translations are disabled, all those available are installed together |
| with the package. However, the environment variable <code>LINGUAS</code> |
| may be set, prior to configuration, to limit the installed set. |
| <code>LINGUAS</code> should then contain a space separated list of locale names |
| (of the form <code><var>ll</var></code> or <code><var>ll</var>_<var>CC</var></code>), |
| stating which languages or language variants are allowed. |
| </p> |
| <p>GNU <code>gettext</code> uses *.its and *.loc files (see section <a href="gettext_16.html#SEC366">Preparing Rules for XML Internationalization</a>) |
| from other packages, provided they are installed in |
| ‘<tt><var>prefix</var>/share/gettext/its/</tt>’, |
| where <code><var>prefix</var></code> is the value of the <code>--prefix</code> option |
| passed to <code>gettext</code>'s <code>configure</code> script. |
| So, this is the canonical location for installing *.its and *.loc files |
| from other packages. |
