Hi,

The POT files published for Drupal 5 RC1 contain an installer.po. This can be used by Drupal in install time from the file system, so that the user can set up Drupal on a translated interface. Since some of the Drupal interface shows up in installation time, the installer.po file shares some strings with other files.

Watch out for the file comments above the strings. If a file comment starts with "(duplicate)", it means that you have a translation for that string already done in a different file, so you can (and should) merge your translations from there.
