vnlog binary package in Ubuntu Focal riscv64

 Vnlog (pronounced "vanillog") is a trivially-simple log format consisting of an
 ASCII table with comments and labelled fields. This package provides tools to
 process and manipulate such logs. The tools are:
 .
 vnl-filter selects a subset of the rows/columns in a vnlog and/or to
 manipulates the contents. This is effectively an awk wrapper.
 .
 vnl-sort, vnl-uniq, vnl-join, vnl-tail and vnl-ts are wrappers around the
 corresponding commandline tools
 .
 vnl-align aligns vnlog columns for easy interpretation by humans
 .
 vnl-make-matrix converts a one-point-per-line vnlog to a matrix of data
