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.
