// You might be wondering why this file is necessary. We have some very specific
//   requirements around our import-flavor builds. They need to look exactly the same as
//   normal builds, but they must immediately open into import mode. So they need a
//   slight config tweak, and then a change to the .app/.exe name (note: we do NOT want to
//   change where data is stored or anything, since that would make these builds
//   incompatible with the mainline builds) So we just change the artifact name.
//
// Another key thing to know about these builds is that we should not upload the
//   latest.yml (windows) and latest-mac.yml (mac) that go along with the executables.
//   This would interrupt the normal install flow for users installing from
//   signal.org/download. So any release script will need to upload these files manually
//   instead of relying on electron-builder, which will upload everything.
