# TODO:
#
#   The FlashTool and FlashToolConsole scripts are messy and should probably we
#   replaced entirely. All these scripts do is try to guess the environment in
#   which to run the Java binary (and they guess wrong on NixOS).
#
#   The FlashTool scripts run 'chmod' on the binaries installed in the Nix
#   store. These commands fail, naturally, because the Nix story is (hopefully)
#   mounted read-only. This doesn't matter, though, because the build
#   instructions fix the executable bits already.
