* Very rough idea
* Remove colour codes
* Work on command for generating docs
* Quick comment
* Use nested collapsible markdown
* Refine documentation command
* Clippy and rename docs
* This layout probably seems best
Also moved some code to documentation.rs to avoid making help.rs massive
* Delete summaries.md
* Add usage strings
* Remove static annotations
* get_documentation produces value
Which will be used like
'help generate_docs | save "something"'
The resulting yaml can be passed to a script for generating HTML/MD files in the website
* Fix subcommands
* DRY code
* Address clippy:
* Fix links
* Clippy lints
* Move documentation to more central location
This changeset contains everything that a separate binary needs to
register its own commands (including the new help function). It is
very possible that this commit misses other pub use exports, but
the contained ones work for our use cases so far.
This improves incremental build time when working on what was previously
the root package. For example, previously all plugins would be rebuilt
with a change to `src/commands/classified/external.rs`, but now only
`nu-cli` will have to be rebuilt (and anything that depends on it).
