# Usage: buildall.bash [-e] [pattern]

#

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

# architectures.

#

# 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.

#

# Options:

# -e: stop at first failure
