#   ADD_JAVAC_FLAGS:=javac flags to append to the default ones.

#   SRC:=one or more directories to search for sources. The order of the source roots

#        is significant. The first found file of a certain name has priority.

#   BIN:=store classes here

#   MODULE:=Name of module being compiled. If set, classes are put in BIN/MODULE.

#   CLASSPATH:=a list of additional entries to set as classpath to javac

#   INCLUDES:=myapp.foo means will only compile java files in myapp.foo or any of its sub-packages.

#   EXCLUDES:=myapp.foo means will do not compile java files in myapp.foo or any of its sub-packages.

#   COPY:=.prp means copy all prp files to the corresponding package in BIN.

#   COPY_FILES:=myapp/foo/setting.txt means copy this file over to the package myapp/foo

#   CLEAN:=.properties means copy and clean all properties file to the corresponding package in BIN.

#   CLEAN_FILES:=myapp/foo/setting.txt means clean this file over to the package myapp/foo

#   SRCZIP:=Create a src.zip based on the found sources and copied files.

#   INCLUDE_FILES:="com/sun/SolarisFoobar.java" means only compile this file!

#       specify files that need to be generated by other rules first.

#   HEADERS:=path to directory where all generated c-headers are written.

#   DEPENDS:=Extra dependecy

#   DISABLE_SJAVAC:=Explicitly disable the use of sjavac for this compilation unit.

#   FAIL_NO_SRC:=Set to false to not fail the build if no source files are found,

#        default is true.

#   DEBUG_SYMBOLS:=Set to false to disable generation of debug symbols.

#   CREATE_API_DIGEST:=Set to true to use a javac plugin to generate a public API

#        hash which can be used for down stream dependencies to only rebuild

#        when the API changes. Implicitly used in sjavac.
