<h2>Analysis And Supplemental Data</h2>
Perhaps the two most interesting datapoints in the above table are SQLite
and SLT. SQLite is a long-running project with long revision chains.
Some of the files in SQLite have been edited over a thousand times.
Each of these edits is stored as a delta, and hence the SQLite project
gets excellent 73:1 compression. SLT, on the other hand, consists of
many large (megabyte-sized) SQL scripts that have one or maybe two
edits each. There is very little delta compression occurring and so the
overall repository compression ratio is much lower. Note also that
quite a bit more bandwidth is required to clone SLT than SQLite.
For the first nine years of its development, SQLite was versioned by CVS.
The resulting CVS repository measured over 320MB in size. So, the
