  # clang release build with some options to enforce useful constraints.
  # Includes dependency checker on an in-source, optimized build.
  # Includes checking @draft etc. API tags vs. ifndef guards like
  # U_HIDE_DRAFT_API and U_FORCE_HIDE_DRAFT_API.
  # (FORCE guards make this tool pass but won't compile to working code.
  # See the testtagsguards.sh script for details.)
