# Usage: $0 [--prefix=LOCATION] [--rc] [--no-jar] [--itest | --itest-nosig] config
#
# Note: The order of the options is important.
#
# --prefix=LOCATION
#       Installation directory.
#       If not specified, uses $SABLEVM_WITH_JIT_LOCATION.
#       If $SABLEVM_WITH_JIT_LOCATION undefined,
#       result to default: $SABLEVM_WITH_JIT_DEFAULT_LOCATION defined
#       in script.
#
# --rc  Reconfigure and rebuild SableJIT without building SableVM.
#       This is useful to avoid recompiling SableVM but to be able to
#       switch configuration of SableJIT to another pre-compiled SableVM
#
# --no-jar
#       Do not put SableJIT files in a jar file.
#       (Partially implemented, you must run installdir manually
#        in SableJIT source directory.)
#
# --itest
#       Turns on inlinability testing
# --itest-nosig
#       Inlinability testing without signals
#
# Environment variable:
#   Set CONFIGURE_OPTIONS to any additionnal options you want
#   to provide to ./configure.
#
#   Set JUNIT_PATH to junit location.  Note if in a jar must have the jar
#   file name included.
