# The boot_cycle.sh script performs two complete image builds (no javadoc though....)
# where the second build uses the first build as the boot jdk.
#
# This is useful to verify that the build is self hoisting and assists
# in flushing out bugs. You can follow up with compare_objects.sh to check
# that the two boot_cycle_?/images/j2sdk are identical. They should be.
#
# Usage:
# Specify the configure arguments to boot_cycle.sh, for example:
#
#    sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server
#
# The same arguments will be used for both builds, except of course --with-boot-jdk
# that will be adjusted to boot_cycle_1 for the second build.
