 The Tor Browser updater supports incremental (binary delta) updates on all
 platforms. However, if the user changes a file that is about to be
 updated, the incremental update will fail, and a full update will be
 downloaded instead. This seems most likely to happen on Linux, where it
 may be common for people to modify their start-tor-browser script with
 custom changes (see #15456). We would like to know how common this is
 among our userbase, so we can determine if we should devote effort into
 #15456 and any other potential similar cases (like torrc changes, for
 example).

 To find this out, we need relative hit counts from one or more of our
 dist.tpo hosts for tor-browser-linux*-4.5a5_*.mar and tor-browser-
 linux*-4.5a4_*.mar.

 4.5a5 was released on March 31st, and 4.5a4 was released on February 25.
 Hit counts for those mar files from the following week or two are probably
 most relevant.
