Subject: [PATCH] [svn-r1929] Added the srcdir option to support concurrent
 tests by different hosts.  Below is the help output for srcdir.     srcdir:  
 Use srcdir option (does not imply other commands)" 		 "snapshot
 srcdir" is equivalent to "snapshot srcdir all" 		 "snapshot
 srcdir checkout" is equivalent to "snapshot checkout"

Also used shell variables to hold directory paths for easier maintenance.
