+Function
+
+   Calculate the strength of selected codon usage bias (S)
+
+Description
+
+   gsvalue calculates the strength of selected codon usage bias (S), also
+   known as Sharp's S index. Using four codon pairs that are recognized by the
+   same tRNA anticodon, namely, Phe(UUC and UUU), Ile(AUC and AUU), Tyr(UAC and
+   UAU), and Asn(AAC and AAU), since the former in each of the pairs has
+   stronger Watson-Crick pairing, selection towards the former codon can be
+   observed for highly expressed genes. S index is therefore the weighted
+   average of such bias, giving an over-all value for a genome, indicating its
+   strength of selected codon usage bias. See Sharp et al. (2005) for details.
+   Sharp originally defined 40 genes as the highly expressed gene group, with
+   tufA, tsf, fusA, rplA-rplF, rplI-rplT, rpsB-rpsT. Since the identificaiton
+   of these genes is not convenient for computational automation, by default,
+   this method uses ribosomal proteins as the highly expressed gene group,
+   as used by Viera-silva and Rocha (2010).
+   However, Sharp's gene group can be optionally used with -sharp option.
+   With this option, all of the 40 genes must be named accordingly in the given
+   genome file.
