duke@2: README-pre-components:
duke@2: ---------------------
duke@2: Current pre-components are langtools, jaxws, jaxp, and corba.
duke@2: 
duke@2: Pre-components can use ant to build but must have a make/Makefile for
duke@2: building (a GNU make Makefile).
duke@2: All ant knowledge is being isolated in the workspaces that use it.
duke@2: 
duke@2: Also for various reasons it is nice to have a Makefile wrapper over the
duke@2: running of ant, but in general having to do
duke@2: anything with shell commands is much easier to do in a Makefile
duke@2: than in an ant script.
duke@2: 
duke@2: The make/makefile rules are:
duke@2: 
duke@2:  Variables:
duke@2:   ALT_BOOTDIR           The jdk home to use to build, if provided
duke@2:   ALT_LANGTOOLS_DIST    The dist area from a langtools build to use, if provided
duke@2:   ALT_OUTPUTDIR         Parent dir of build and dist directories, if provided
duke@2:   VARIANT               If DBG, debug build, if OPT, optimized build
jjg@113:   TARGET_CLASS_VERSION  The classfile version number (currently 7)
duke@2:   ANT_HOME              Home of ant to use, if provided
duke@2:   QUIET                 If defined, be quiet
duke@2:   VERBOSE               If defined, be verbose
duke@2:   JDK_VERSION           Version being built
duke@2:   FULL_VERSION          Full version string for this jdk build
duke@2:   MILESTONE             fcs, beta, internal or empty
duke@2:   BUILD_NUMBER          Number of the jdk build
duke@2:   JPRT_ARCHIVE_BUNDLE   Path to zip bundle to create for JPRT
duke@2: 
duke@2:  Targets:
duke@2:   all                   Build everything, including dist
duke@2:   build                 Build build area
duke@2:   clean                 Clean up
duke@2:   clobber               Same as clean (don't ask)
duke@2:   sanity                Perform any sanity checks, exit non-zero if errors
duke@2:   jprt_build_product    JPRT product build, zip results into JPRT_ARCHIVE_BUNDLE
duke@2:   jprt_build_debug      JPRT debug build, zip results into JPRT_ARCHIVE_BUNDLE
duke@2:   jprt_build_fastdebug  JPRT fastdebug build, zip results into JPRT_ARCHIVE_BUNDLE
duke@2: 
duke@2: Then of course we expect a dist/lib/classes.jar, dist/lib/src.zip and dist/lib/bin.zip.
