# 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.
