Usage langtool --options langfile

  For all actions, the modified langfile will be output on stdout. When doing
  stuff to english.lang, you should almost always apply the same change to all
  other languages to avoid bothering translators.

  --deprecate --id ID_1,ID_2 --id ID_3 langfile

    Deprecate a number of ids.
    Example: langtool --id LANG_LEFT,LANG_RIGHT --LANG_BOTTOM english.lang

  --changesource --id ID --target target --to string langfile
    
    Change the source text of a specific string specified by id and target. Use
    this on all langfiles if you're changing a source in english.lang that
    doesn't need attention from translators (case changes etc.).
    Example:
      langtool --changesource --id LANG_OK --target e200 --to "OK" english.lang

  --changeid --from LANG_LFET --to LANG_LEFT langfile
    
    Change the name of an ID. THIS WILL BREAK BACKWARDS COMPATIBILITY. Use with
    extreme caution.
    Example: langtool --changeid --from LANG_OK --to LANG_YES english.lang

  --changedesc --to string --id LANG_LEFT langfile

    Change the desc for an ID.
    Example: langtool --changedesc --to "New desc" --id LANG_OK english.lang

  --changetarget --from target --to target --id ID1 langfile

    Change the target for the specified id from one value to another
    Example:
      langtool --changetarget --from e200 --to e200,c200 --id LANG_ON dansk.lang
