    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.
