+    (description
+     "CheckM provides a set of tools for assessing the quality of genomes
+recovered from isolates, single cells, or metagenomes.  It provides robust
+estimates of genome completeness and contamination by using collocated sets of
+genes that are ubiquitous and single-copy within a phylogenetic lineage.
+Assessment of genome quality can also be examined using plots depicting key
+genomic characteristics (e.g., GC, coding density) which highlight sequences
+outside the expected distributions of a typical genome.  CheckM also provides
+tools for identifying genome bins that are likely candidates for merging based
+on marker set compatibility, similarity in genomic characteristics, and
+proximity within a reference genome.")
