+description = """
+chewBBACA is a software suite for the creation and evaluation of core genome and
+whole genome MultiLocus Sequence Typing (cg/wgMLST) schemas and results.
+The "BBACA" stands for "BSR-Based Allele Calling Algorithm".
+BSR stands for BLAST Score Ratio as proposed by Rasko DA et al.
+The "chew" part adds extra coolness to the name and could be thought of as
+"Comprehensive and Highly Efficient Workflow"."""
