/*!
generating the source codes that is used by [flood-tide](https://crates.io/crates/flood-tide).

# Features

- generate tables that is used by [flood-tide](https://crates.io/crates/flood-tide)
- easy to use by xtask
- parsing text define format file that has command options like help text
- minimum support rustc 1.57.0 (f1edd0429 2021-11-29)

# Todos

- [ ] adding test codes
- [ ] other define format support  (like yaml,json)

# Supports

- [flood-tide](https://crates.io/crates/flood-tide) - command option parsing
- [aki-gsub](https://crates.io/crates/aki-gsub) - the sample used *flood-tide*
