"""A utility command to make zip file and tgz file.

When the version is 1.2.3.4, the following command creats output.zip and
output.tgz which have these three files.
  hoge-fuga-1.2.3.4/foo1
  hoge-fuga-1.2.3.4/foo2
  hoge-fuga-1.2.3.4/bar/piyo

Example usage:
  python archive_files.py \
    --base_path=/path/to/base_path/ \
    --zip_output=/path/to/output.zip \
    --tgz_output=/path/to/output.tgz \
    --version_file=../../mozc_version.txt \
    --top_dir_base=hoge-fuga
    /path/to/base_path/foo1 \
    /path/to/base_path/foo2 \
    /path/to/base_path/bar/piyo
