The `author/author_handle.json` file content was generated
by the commands:
```sh
cd tmp
rm -rf ../author
./gen_author_json.sh author_handle.txt author.csv author-wins.csv ../author
```
Also installed is `author/README.md` that describes the `author/`
directory tree and author_handle.json format.
Some tmp files were slightly modified before to help the
`gen_author_json.sh` tool.
NOTE: The `gen_author_json.sh` tool is under the `tmp/` directory
and **NOT** the `bin/` directory. Like the files under tmp/`
directory, the `gen_author_json.sh` tool will go away as the files
and tool are not needed.
The `author/author_handle.json` files will become authoritative,
replacing the `gen_author_json.sh` tool and files under tmp/`
directory. However we will keep them around for a while, at least
a git of time after issue #4 is resolved.
