 The majority of the Genome Browser source code is available under the
 MIT license, see 
 <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/LICENSE" target=_blank>the file LICENSE in our
 source code repository</a>. As such, the Unix command line utilities needed to build tracks and track hub
 files, or that can be part of computational pipelines except BLAT/liftOver, and our
 hundreds of tools to filter , sort, rearrange, join and process genome
 annotation files, can be used by anyone freely and they can be redistributed
 via package managers and installation tools, even for commercial use.  
 Notable examples are bedToBigBed, wigToBigWig, overlapSelect, featureBits,
 pslMap, pslFilter and pslCDnaFilter.  </p>
