-Bio++ is a set of C++ libraries for Bioinformatics, including sequence
-analysis, phylogenetics, molecular evolution and population genetics.
-Bio++ is Object Oriented and is designed to be both easy to use and
-computer efficient. Bio++ intends to help programmers to write
-computer expensive programs, by providing them a set of re-usable
-tools.
-
-This contains the Bio++ 1.9 (April 2010) Seq Library. It can be
-installed along the current Bio++ suite libraries, however they better
-not be present at compile time.

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.
-# Line up the first '|' above the ':' following the base package name, and
-# the '|' on the right side marks the last column you can put a character in.
-# You must make exactly 11 lines for the formatting to be correct.  It's also
-# customary to leave one space after the ':' except on otherwise blank lines.
