<p>Most programs are written and documented in English, and primarily use English to interact with users. This is also true for a great deal of web sites. However, most people are less comfortable with English than with their native language, and would prefer to use their mother tongue as much as possible. Many people love to see their web site showing a lot less English, and far more of their own language. Therefore Drupal provides a framework to setup a multi-lingual web site, or to overwrite the default English texts.</p>
<h3>How to interface translation works</h3>
<p>Whenever Drupal encounters an interface string which needs to be displayed, it tries to translate it into the currently selected language. If a translation is not available, then the string is remembered, so you can look up untranslated strings easily.</p>
<p>Drupal provides two options to translate these strings. First is the integrated web interface, where you can search for untranslated strings, and specify their translations via simple web forms. An easier, and much less time consuming method is to import translations already done for your language. This is achieved by the use of GNU gettext Portable Object files. These are editable with quite convenient desktop editors specifically architected for supporting your work with GNU Gettext files. The import feature allows you to add strings from such files into the site database. The export functionality enables you to share your translations with others, generating Portable Object files from your site strings.");
