# TP3 tpshell - two-phase ISO build, exactly the proven CocoGm2 recipe.
#   Phase 1: -fgen-module-list=modules.lst   (generates the import closure list)
#   Phase 2: -fuse-list=modules.lst          (links using that list)
# This avoids gm2's whole-program pass-3 identifier cap on compiler-size programs.
