# Template to package a shared library into a Mac framework bundle.
#
# This template provides two targets to control whether the framework is
# merely built when targets depend on it, or whether it is linked as well:
# "$target_name" and "$target_name+link".
#
# See the //build/config/mac/base_rules.gni:framework_bundle for a discussion
# and examples.
#
# Arguments
#
#     info_plist:
#         (optional) string, path to the Info.plist file that will be used for
#         the bundle.
#
#     info_plist_target:
#         (optional) string, if the info_plist is generated from an action,
#         rather than a regular source file, specify the target name in lieu
#         of info_plist. The two arguments are mutually exclusive.
#
#     output_name:
#         (optional) string, name of the generated framework without the
#         .framework suffix. If omitted, defaults to target_name.
#
#     framework_version:
#         (optional) string, version of the framework. Typically this is a
#         single letter, like "A". If omitted, the Versions/ subdirectory
#         structure will not be created, and build output will go directly
#         into the framework subdirectory.

#         (optional) string array, 'key=value' pairs for extra fields which are
#         specified in a source Info.plist template.
