POFileConsistency — checks consistency in a collection of PO files
POFileConsistency  [OPTION] [...] [FILE] [...]
--help or -h
        --interactive or -i
        --equivalent=file or
          -e file
        --only-empty or -o
        --match=string or
          -m string
        --strip-chars=chars or
          -r chars
        In interactive mode you iterate through each of the inconsistencies found. In each prompt you can press Enter to ignore this inconsistency, a number of a possible translation (1, 2, ...) to change all the translations to that text, 0 to input a text to use in all the translations, l to add the exception to each of the PO files, or, if you are using at least one equivalents file, a to add the exception to the first of those files.
      POFileConsistency recognizes several PO file
      header directives. As with all gettext lint tools, these directives
      are all prefixed with X-POFile.
