As an aside, the format for Deadwood snapshots is Deadwood-H-YYYYMMDD-N.tar.bz2
Here, “H” stands for “Head” (there is also the occasional “Deadwood-S-... snapshot where “S” stands for “Stable”), “YYYY” is the year (2010), “MM” is the month, “DD” is the day, and “N” is the release number for that day (usually 1, but sometimes I release two or three Deadwood snapshots on a given day).
