Easily create custom, giant-sized calendars.
The basic idea is that a calendar is built using a template of what each date is supposed to look like.
Still has some work to do but this is a good start.
Requires RMagick to be installed.
If you are on a Mac and use homebrew (both should be true), you can install it with:
Install ImageMagick library brew install imagemagick
Install the Ruby gem gem install rmagick
It should then work fine, but if you get an error about annotate not having the necessary font, run:
brew install ghostscript
