# This action takes an archive (.a) file and unpacks it unto object (.o) files.
# The following input gyp variables are required:
#   unpack_lib_output_dir, the output directory of extracted object file
#   unpack_lib_name, 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'...]
#
# For example:
#   'variables': {
#     'unpack_lib_search_path_list': [
#       '-a', '/a/lib.a',
#       '-a', 'b/lib.a',
#     ],
#     'unpack_lib_output_dir':'ouput',
#     'unpack_lib_name':'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.
