 8.4.2 Using Compendia
 ---------------------
 
    You can use a compendium file to initialize a translation from
 scratch or to update an already existing translation.
 
 8.4.2.1 Initialize a New Translation File
 .........................................
 
    Since a PO file with translations does not exist the translator can
 merely use ‘/dev/null’ to fake the “old” translation file.
 
      msgmerge --compendium compendium.po -o file.po /dev/null file.pot
 
 8.4.2.2 Update an Existing Translation File
 ...........................................
 
    Concatenate the compendium file(s) and the existing PO, merge the
 result with the POT file and remove the obsolete entries (optional, here
 done using ‘msgattrib’):
 
      msgcat --use-first -o update.po compendium1.po compendium2.po file.po
      msgmerge update.po file.pot | msgattrib --no-obsolete > file.po
