    Check passphrase quality.
    For each passphrase to check, pwqcheck reads up to 3 lines from standard input:
      first line is a new passphrase,
      second line is an old passphrase, and
      third line is either an existing account name or a passwd entry.
    Usage: pwqcheck [options]
    Valid options are:
      min=N0,N1,N2,N3,N4
           set minimum allowed lengths for different kinds of passphrases;
      max=N
           set maximum allowed passphrase length;
      passphrase=N
           set number of words required for a passphrase;
      match=N
           set length of common substring in substring check;
      config=FILE
           load config FILE in passwdqc.conf format;
      -1
           read just 1 line (new passphrase);
      -2
           read just 2 lines (new and old passphrases);
      --multi
           check multiple passphrases (until EOF);
