# Calls javac with the -bootclasspath values passed in automatically.
# (This avoids having to manually set a boot class path).
# If $JAVAC is set, it will call that instead of 'javac'.

#
# Script-specific args:
# --mode=[host|target|jvm]:
# Select between host,target,jvm bootclasspath (default target).
# --core-only: Use only "core" bootclasspath (e.g. do not include framework).
# Ignored with --mode=jvm.
# --show-commands: Print the javac command being executed.
# --help: Print above list of args.
#
# All other args are forwarded to javac
