+#
+# 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
