`Docsetzilla` is a backbone that builds all docsets for POSH TUI client. 

In its infancy, it was just a bunch of scripts on top of YARD and BunnyCDN. But this baby is growing up and now has more tricks up its sleeve. I introduced a bunch of improvements to build docsets faster, but the biggest new feature is **support for RDoc**.

Docsetzilla is powered by two gems:
- [yard-markdown](https://github.com/skatkov/yard-markdown) gem for YARD
- [rdoc-markdown](https://github.com/skatkov/rdoc-markdown/) gem for RDoc

Why support both? YARD claims to support RDoc, but a lot of useful information is still lost in the process. I'm looking to make this tool as informative as possible, and losing such vital data points seemed unacceptable.

[The new RDoc maintainer stated that markdown support is a priority](https://st0012.dev/a-rdoc-maintainer-s-view-on-ruby-s-documentation) for the project going forward. I have also seen an active group on Bundler Slack that is dedicated to improving RDoc. I would like to [dive deeper into markdown parser issues](https://github.com/ruby/rdoc/issues?q=is%3Aissue+is%3Aopen+label%3Amarkup-markdown) that RDoc is currently battling with.
