+Sometimes a fileset included in a distribution will be found to be invalid, for example by being published with the wrong checksum.  The distribution protocol doesn't provide a way to tell the client to give up on a fileset, so these problems are currently just announced by email.  If this happens you will have to manually edit ''download_failures.csv'' to remove the offending file; otherwise ''update_mirror.py'' will try to download it each time it runs.
+
+If you only want part of a distribution, for example only the 'camera' stage, you can modify ''update_mirror.py'' to ignore the rest.  The easiest place to do this is the clause in the routine ''fetchUpdates'' where culledProductList is constructed.  Each entry in productList is a dictionary containing all the columns of the table describing the filesets; simply exclude the filesets you don't want from culledProductList.  Note that there is no way to keep track of the excluded filesets between runs, though- if you want them later you will have to manually adjust the script and ''product_status.csv'' to go back and re-download filesets from that time interval.
