# This action takes an archive (.a) file and unpacks it unto object (.o) files.
# The following input gyp variables are required:
#   unpack_lib, the library to unpack.
#   object_file_output_dir, the output directory of extracted object file.
#   object_file_to_extract, the object file to be extracted.
#   unpack_lib_search_path_list, a list of paths to search for the library.
#   it must be ['-a', 'path_name1', '-a', 'path_name2'...]
#   TODO(fgalligan): Change unpack_lib_posix.sh to expect only one input
#                    library to unpack.
#
# For example:
#   'variables': {
#     'unpack_lib_search_path_list': [
#       '-a', '/a/lib.a',
#       '-a', 'b/lib.a',
#     ],
#     'object_file_output_dir':'output',
#     'object_file_to_extract':'offsets.o'
#   },
#   'includes': ['unpack_lib_posix.gypi'],
#
# It unpacks the first existing library in 'unpack_lib_search_path_list', and
# extracts 'offsets.o' to 'output' directory.
