405#   SRC:=one or more directories to search for sources. The order of the source roots
406#        is significant. The first found file of a certain name has priority.
407#   BIN:=store classes here
408#   CLASSPATH:=a list of additional entries to set as classpath to javac
409#   INCLUDES:=myapp.foo means will only compile java files in myapp.foo or any of its sub-packages.
410#   EXCLUDES:=myapp.foo means will do not compile java files in myapp.foo or any of its sub-packages.

414#   CLEAN_FILES:=myapp/foo/setting.txt means clean this file over to the package myapp/foo
415#   SRCZIP:=Create a src.zip based on the found sources and copied files.
416#   INCLUDE_FILES:="com/sun/SolarisFoobar.java" means only compile this file!
417#   EXCLUDE_FILES:="com/sun/SolarisFoobar.java" means do not compile this particular file!

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