# To use this, create a gyp target with the following form:

#   'type': 'none',
#   'variables': {
#     'package_name': 'my-package',
#     'java_in_dir': 'path/to/package/root',
#   },
#   'includes': ['path/to/this/gypi/file'],
# }
#
# Note that this assumes that there's ant buildfile with package_name in
# java_in_dir. So if if you have package_name="base" and
# java_in_dir="base/android/java" you should have a directory structure like:
#
# base/android/java/base.xml
# base/android/java/org/chromium/base/Foo.java
# base/android/java/org/chromium/base/Bar.java
#
# Finally, the generated jar-file will be:
#   <(PRODUCT_DIR)/lib.java/chromium_base.jar
#
# TODO(yfriedman): The "finally" statement isn't entirely true yet, as we don't
# auto-generate the ant file yet.
