[Climate](https://github.com/gridbugs/climate) is a declarative command-line parser for OCaml. This release is mostly focused on improving `--help` messages and allowing the colours of help messages to be configured.

### Added

- Allow help messages colours to be configured ([#7](https://github.com/gridbugs/climate/pull/7))
- Proof of concept of manpage generation (disabled in release as it’s very incomplete) ([#11](https://github.com/gridbugs/climate/pull/11))

### Changed

- Changed default help message colour scheme to be more colour-blind readable  
and more visible on light and dark terminals ([#7](https://github.com/gridbugs/climate/pull/7))
- Changed description of `--help` argument.

### Fixes

- Remove superfluous style reset escape sequences ([#7](https://github.com/gridbugs/climate/pull/7))
- Don’t apply formatting to trailing spaces in argument names in help messages ([#8](https://github.com/gridbugs/climate/pull/8))
- Print a readable error when the argument spec is invalid ([#10](https://github.com/gridbugs/climate/pull/10))
