[quilt](https://wiki.debian.org/UsingQuilt):
1. In the root directory of `debcargo-conf`, `cd build/foo`
2. `quilt series` to check existing patches, `quilt push -a` to test apply all
of them, and `quilt pop -a` to unapply them
3. `quilt new patch-name.patch` to create a new patch, `quilt edit
path/to/file` to edit a file with changes saved in current patch, `quilt
header -e --dep3` to add a DEP-3 patch header
4. `quilt refresh` to update current patch and prevent fuzz (we don't allow
fuzzes when building)
5. `cp -r debian/patches ../../src/foo/debian/` to copy updated patches over
6. In root directory, run `./update.sh foo` to update the build directory
Note that `update.sh` deletes and re-creates `build/foo`, so an open terminal
in it needs to go up and down into the new directory.
