    25 # The boot_cycle.sh script performs two complete image builds (no javadoc though....)

    26 # where the second build uses the first build as the boot jdk.

    27 #

    28 # This is useful to verify that the build is self hoisting and assists

    29 # in flushing out bugs. You can follow up with compare_objects.sh to check

    30 # that the two boot_cycle_?/images/j2sdk are identical. They should be.

    31 #

    32 # Usage:

    33 # Specify the configure arguments to boot_cycle.sh, for example:

    34 #

    35 #    sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server

    36 #

    37 # The same arguments will be used for both builds, except of course --with-boot-jdk

    38 # that will be adjusted to boot_cycle_1 for the second build.
