 The pre-compiled user application binaries may function on your system
 without this build procedure.  For example to obtain the
 linux.x86_64 binaries:
  rsync -azvP rsync://hgdownload.soe.ucsc.edu/genome/admin/exe/linux.x86_64/ ./
 
 Mac OSX binaries available via:
  rsync -azvP rsync://hgdownload.soe.ucsc.edu/genome/admin/exe/macOSX.x86_64/ ./
 
 Most source code users will only be interested in the kent/src/inc and
 kent/src/lib directories, which contain the interfaces and implementations
 to the library routines,  and in a few specific applications.
 The applications are scattered in other directories.  Many of them are web based.
 The UCSC Genome Browser in particular is mostly found in kent/src/hg/hgTracks.
 
+The current version number is stored in src/hg/inc/versionInfo.h .
+The current version of a running genome browser is displayed in the html
+page <TITLE> by every CGI program, e.g. http://genome.ucsc.edu/cgi-bin/hgTracks, 
+in modern internet browser hover over a tab to show it.

 1. Get the code.  The best way to do this now for
    Unix users is via Git following the instructions at:
      http://genome.ucsc.edu/admin/git.html
    Or, fetch the entire source in a single file:
      rsync -azvP rsync://hgdownload.soe.ucsc.edu/genome/admin/jksrc.zip ./
      or:
      wget --timestamping http://hgdownload.soe.ucsc.edu/admin/jksrc.zip
    The unzip result from that file will establish a directory hierarchy:
      ./kent/...
