 udcCache means URL-Data-Cache
 
-BBI files use the udcCach.
+BBI files use the udcCache.
 BBI means Big Binary Indexed and includes
 file types such as BigBed (.bb) and BigWig (.bw).
 
 UCSC BAM file support may also use the udcCache
 
 The udcCache allows tracks that are either installed tracks
 or custom tracks of the above mentioned types to cache data 
 that they have already fetched via URL.  This allows data to 
 reside elsewhere and only download the parts
 needed on demand.  The datablocks are usually
 compressed and have an efficient random access
 index. They are accessed from a remote location
 via URLs such as HTTP, HTTPS, FTP.
 
 By default, udcCache stores files in /tmp/udcCache
 
 Howver, you may include the following in your hg.conf
 and then let your regular trash cleaning scripts
 clean out the old udcCache automatically as well:
 
 # directory for temporary bbi file caching
 udc.cacheDir=../trash/udcCache
 
 Notice that this path is relative to your 
 cgi executable directory which is the 
 current directory when the cgi starts up.
 On some systems this directory is called cgi-bin/.
