To make it easier to install

Hi! This is a great idea and I'm actually very fond of it.

There is an attempt to making conky compatible with Homebrew.

The idea is to create a formula similar to conky-all (linux). The only difference will be, support for parts not available to macOS, such as systemd, will be missing.

Currently, we need to solve these 2 issues to achieve a conky-all formula for macOS:

• Getting cairo-conky working (see #2)
• Getting xmms2 working (see #1)
• Get 80+ stars on this github project (otherwise Homebrew will not accept our project)

One temporary solution would be to create 2 formulas: conky, conky-all. One would be a cut-down version with only the parts currently working and the other would be a development version.

I am thinking of doing the first once I find some free time, but I may need some help for the latter.
