SYNTAX
mergetr myapp_de.po myapp.po
DESCRIPTION
When the texts in your program change as it is developed, a the base .po file can be regenerated using findtr, then mergetr can be used to merge the changes into the other .po files:
mergetr myapp_de.po myapp.po
mergetr myapp_fr.po myapp.po
mergetr myapp_ja.po myapp.po
The translation team then edits the new .po files to translate the new or changed texts. When texts change, the old text is included in the .po file as a comment to guide the new translation (no "fuzzy" matching is done).
