-  msgmerge updated-po-file reference-file > output.po+  msgmerge up_to_date_po-file target_po-file > output.po
  
-The result in output.po contains the reference-file with the new translated strings from the updated-po-file.+The result in output.po contains the target_po-file with the new translated strings from the up_to_date_po-file.
  
-This tool can be used to merge strings from the development branch towards a stable branch or vice-versa.+This tool can be used to merge strings from a stable branch into the development branch (or vice versa).
  
-Example with a PO file:+A specific example is probably handy. Suppose you have a Dutch translation file for a package called "packageW". 
  
-  msgmerge ~/Downloads/fr.po fr.po > fr.po.new +This is fully translated in the stable "Xfce 4.8" and needs to be merged with an incomplete Dutch translation file in the development branch "master". Goal: prevent unnecessary work in translating the development branch.
-  mv fr.po.new fr.po+
  
-Note that you cannot send the output directly on fr.po because it will fail with an 100% untranslated PO file.+Both files are in the directory Downloads of your home directory, which is the usual location of downloaded files. 
 + 
 +Copy/paste the following command in your terminal: 
 + 
 +  cd Downloads 
 + 
 +(press Enter) 
 + 
 +Now copy/paste the following command in your terminal: 
 + 
 +  msgmerge packageW-xfce-4-8.nl.po packageW-master.nl.po > NEWpackageW-master.nl.po 
 + 
 +(press Enter) 
 + 
 +Then delete both "packageW-xfce-4-8.nl.po" (you don't need it anymore) and "packageW-master.nl.po" (you don't want a name conflict in the next step). 
 + 
 +Then rename "NEWpackageW-master.nl.po" to "packageW-master.nl.po". 
 + 
 +Finally: upload "packageW-master.nl.po" in Transifex. 
 + 
 +Note that you cannot send the output directly to "packageW-master.nl.po", as it will fail with a totally unchanged PO file (because of the name conflict).
