 If you want to run a local installation of the UCSC Genome Browser
 (we call this a mirror, even when it includes only a small 
 part of the data), you do not need the whole source tree. We provide
 statically compiled binary CGI-bin executables, the apache htdocs folder, 
 binary MySQL databases and ancillary large data files in /gbdb via an Rsync
 download server. For install details see http://genome.ucsc.edu/admin/mirror.html
 
 Most source code users will only be interested in the src/inc and 
 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 src/hg/hgTracks.
