   alword: frequency and information of aligned words

   alword(words: in, symvec: out, output: out)

   words:  Aligned words.  Since the input is usually to be a UNIX dictionary,
      there need not be any header lines.  However, if they exist, they must
      begin with an asterisk '*'.

      The remaining lines are used for the words.

   alwordp: parameters to control the program.  If the file is empty
      defaults are used.
      If the first line begins with the letter `e' then the words are
      aligned by their last character.
      If there is a first line, the second line must have the maximum
      word length to be included in the calculation.  Words longer than
      this will be skipped (and reported to output).

      If the first character of the second line is 'a' then all of the
      words in the file will be read.  Otherwise, only the first
      word on each line will be read.
   symvec:  table of frequencies and information content.  The information
      measure is corrected for small sample size (Schneider et al, 1986).
   output: messages to the user

   Take an aligned set of protein sequences and produce input to the
   consensus program for producing a logo.


* This is an example sequence.
* This is the second example sequence.
* It is the last one.
