 3updateucsc.sh is a shell script to facilitate the updates from UCSC.
 4Galaxy stores several files locally to speed up operations that depend
 5on information from UCSC.  These files can all be found in the
 6static/ucsc folder.

 8Before adding updateucsc.sh to the crontab, it is important to note
 9two things.  First, updateucsc.sh must be edited to point towards the
10root galaxy directory.  At the top of the file there is a variable
11"GALAXY" that should be edited.  Second, the updates come from UCSC
12via their table browsers.  While the tendency is typically to run cron
13jobs late at night, UCSC, like most, tend to take down their servers
14at odd hours for maintenance.  The update scripts for UCSC are not CPU
15intensive, and should be scheduled during normal hours.
