%description
Bindings to edlib, a lightweight performant C/C++ library for exact
pairwise sequence alignment using edit distance (Levenshtein distance).
The algorithm computes the optimal alignment path, but also can be used to
find only the start and/or end of the alignment path for convenience.
Edlib was designed to be ultrafast and require little memory, with the
capability to handle very large sequences. Three alignment methods are
supported: global (Needleman-Wunsch), infix (Hybrid Wunsch), and prefix
(Semi-Hybrid Wunsch). The original C/C++ library is described in "Edlib: a
C/C++ library for fast, exact sequence alignment using edit distance", M.
Šošić, M. Šikić, <doi:10.1093/bioinformatics/btw753>.
