-Release 2.2.  (Note: large data sets like "_data/BVZ-tsukuba0.max" are VERY MEMORY INTENSIVE and cannot be run on 8 GB machines; for that data set you will need over 128 GB of memory.)

 <h2>Prior Versions</h2>
 
 The original port of the C source code is in the subdirectory [v1.2][v1.2]. It is used in an example command-line program cmd/pseudo/main_v1.2.go.  It is fine for command-line or utility programs, but it is not safe for concurrent use in a server.
