# tooledit is a Tk/BWidget application; headless builds (--disable-gui)
# do not build or run any of the Tk tooling.  Skip when the required
# Tcl environment is unavailable.  BWidget pulls in Tk on load, which
# needs a display, so probe under xvfb-run; the explicit exit is needed
# because 'package require' errors do not reliably set tclsh's exit
# code when reading commands from stdin.  Probe on server number 95:
# xvfb-run's default is 99, and test.sh's plain xvfb-run would race a
# lingering Xvfb on the same display.
