  27 # This file makes modifications to module-info.java files based on the build
  28 # configuration.
  29 #
  30 # Depending on build platform, imported modules and optional parts of the build
  31 # being active, some modules need to have extra exports, provides or uses
  32 # declarations added to them. These optional extras are defined in .extra files:
  33 #
  34 # src/<module>/<share,platform>/classes/module-info.java.extra
  35 #
  36 # The contents of the .extra files are simply extra lines that could fit into
  37 # the module-info file.
  38 #
  39 # This makefile is called once for each from-module with the variable
  40 # MODULE naming the from-module.
  41 #
  42 # The modified module-info.java files are put in the gensrc directory where
  43 # they will automatically override the static versions in the src tree.
