Function

   Calculates fractional GC content of nucleic acid sequences

Description

   This calculates the fraction of G+C bases of the input nucleic acid
   sequence(s).

   It reads in nucleic acid sequences, sums the number of 'G' and 'C'
   bases and writes out the result as the fraction (in the interval 0.0
   to 1.0) of the length of the whole sequence.

Usage

   Here is a sample session with geecee
