8.4 Using Translation Compendia
A compendium is a special PO file containing a set of translations recurring in many different packages. The translator can use gettext tools to build a new compendium, to add entries to her compendium, and to initialize untranslated entries, or to update already translated entries, from translations kept in the compendium.
| • Creating Compendia: | Merging translations for later use | |
| • Using Compendia: | Using older translations if they fit |
