31r"""A script to embed the given (relative) path name to C/C++ characters array.
32
33Example:
34  ./embed_pathname.py --path_to_be_embedded=d:\data\mozc
35      --constant_name=kMozcDataDir --output=mozc_data_dir.h
36  Then you will get 'mozc_data_dir.h' which consists of the following line.
37      const char kMozcDataDir[] = "d:\\data\\mozc";
