[ANN] brisk 0.2.1 released

brisk verison 0.2.1 has been released

docs: <https://github.com/frankieleef/brisk>

Brisk is a tiny Ruby development environment for Mac users. When using
Brisk, there's no need for a webserver and no need for configuration.
Brisk starts a Caddy webserver on startup and will proxy all your
*.dev domain requests to the sites installed on your local machine
using DnsMasq. The only thing Brisk needs is a config.ru file. Brisk
supports both HTTP and HTTPS. Any certificate created will be trusted
by your browser as well.

Changes

- A safer way of determining if a server is already running
- A safer way of checking the pid's of the server processes
- Various bugfixes
