+These **seq**uences **wish** they were squished into a graph.
+
+seqwish implements a lossless conversion from pairwise alignments between sequences to a variation graph encoding the sequences
+and their alignments. As input we typically take all-versus-all alignments, but the exact structure of the alignment set may
+be defined in an application specific way. This algorithm uses a series of disk-backed sorts and passes over the alignment
+and sequence inputs to allow the graph to be constructed from very large inputs that are commonly encountered when working with
+large numbers of noisy input sequences. Memory usage during construction and traversal is limited by the use of sorted
+disk-backed arrays and succinct rank/select dictionaries to record a queryable version of the graph.
