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