 everything looks OK to us (note that we are not Perl experts).  Nice work!

 Thanks for reviewing this.

 > You might consider adding a -q parameter when you exec
 make_incremental_update.sh (unless you think you need it for debugging).
 We added support for -q because the Mozilla scripts are very chatty.

 We are not displaying the output of the script, so it's not a problem that
 it is chatty.

 then verifies against other developers' builds (to check reproducibility).

 Yes. The new MAR files are added to the gitian/$version directory, so
 running hash-bundles.sh again should update the sha256sums.txt with the
 new files. However, it will add a mismatch with other developers who did
 not generate the incremental MAR files, so I'm wondering if it would be
 better to add them to a separate sha256sums file.
