I recently downloaded a textbook as a .djvu file (sighs, not a PDF. wth is this). I found a way to view it and a way to convert it on the Internet (cool).
Recently however, I downloaded Homebrew for my Mac, and I found a strange file that was called djvu2pdf.rb (this sounds like it does what I want it to do) inside of the folder ~/homebrew/Library/Formula.
Among the spotlight search for djvu I did were these files:
What is this file for? Does it have anything to do with converting a .djvu to a .pdf? If so, how do I use it?

In Homebrew's terminology, a "formula" is a set of instructions written in the Ruby programming language to install a software with Homebrew (which is also written in Ruby.) It is not the software you want to install itself. – nodakai – 2014-01-23T01:55:20.363
Now that I've installed it, since there is no help from the manpages or online about what the app does, where do I find this application on my computer? I can't run it from the command line because I don't know how it operates.

Basically Homebrew provides a bunch of formulas, which (as nodakai said) are Ruby scripts that install software from various places. The actual files belonging to each package are located in
– echristopherson – 2014-01-23T23:30:20.940/usr/local/Cellar/<formula_name>/<version>-- or in your case,~/homebrew/Cellar/<formula_name>/<version>. If Homebrew's installed in the default place, they then get symlinked into/usr/local/{lib,share,bin,etc.}; but since you have it in~/homebrewI'm not sure where the links go.
