#
# buildall.bash builds the standard library for all Go-supported

#
# Originally the Go build system used it as a smoke test to quickly
# flag portability issues in builders named "misc-compile" or "all-compile".
# As of CL 464955, the build system uses make.bash -compile-only instead,
# so this script no longer runs in any automated fashion.

# -e: stop at first failure
