## Gopher
[_Gopher_](https://en.wikipedia.org/wiki/Gopher_(protocol)) is a communications protocol that, in the early 90s, competed (briefly) with what became the world wide web. _Gopher_ serves up files and text based menus. As such, it is much lighter weight than HTML documents and the like served over http. Due to its text based nature it also has the benefit of being reliable in its visual output and style, and for being relatively accessible.

## Installation

Burrow requires python3 to be installed on the system prior to running.
Until some bundling/setup-file creation occurs, you will also need to add:
    
    pip3 install pillow
    

On some linux distributions an additional package for tkinter may be required.
If you get a console error complaining about tkinter try the following (or equivalent for your package manager):

    sudo apt-get install python3-tk
    sudo apt-get install python3-pil.imagetk
    

## Distribution

Burrow's primary system target is debian based linux systems. Once a version 1.0 is reached the plan is to distribute via .DEB packages and possibly through snapcraft (if a workable bundle can be figured out).

Some version of windows executable may come along as well, depending on configurability of build tools (py2exe, freeze, etc) for windows executables and time.


## Contribute

To contribute, please branch off of `develop` and then submit a pull request into `develop` with any changes. As the project grows I will likely add wiki, issues, etc as the need arises and more people get involved.
