Translations:Help:Extension:Translate/Off-line translation/7/en

The files are standard Gettext PO files with some extra information. The header contains some extra fields shown below; the  for each message contains an identifier that the Translate extension needs. Some editors are known to strip either the header comments or the  lines, so start with a small file to make sure that your editor does not remove these – it's not funny to realize the editor was buggy after translating hundreds of messages that you cannot import back into the online system! The message documentation is exported as translation comments.
