**Note:**

* Line wrapped is enabled with a maximum line length of 85 characters.
This could be adjusted in the source code (`HowdoiHandler.MAX_LINE_LENGTH`).

* *Howdoi* generally perform better if you ask a question using keywords
instead of a complete sentences (eg: "How do i make a decorator in Python"
-> "python decorator").

* __[*Limitation*]__ If a answer contains multiple code blocks, the `@howdoi`
and `@howdowe` commands would only return the first coding section, use
`@howdo[we|i]!` in that case.
