### Build Dependencies and Installation

It should be possible to build this project for most platforms using cargo
directly. Installation and XScreensaver integration probably only works on UNIX
machines (Linux, \*BSD, etc). It's only been developed and tested on Debian
jessie, using the stable Rust toolchain (version 1.9).

A patched version of the `glutin` OpenGL window generation library is required;
see below.

The `pandoc` tool is required for building manpages.

To just build (`--debug`) and run an indivual "hack", eg `exuberantbovines`:

    cargo run --bin exuberantbovines

To build everything (`--release`) and install, first run:

    make install

Then follow the directions about adding lines like the following to you
`~/.xscreensaver` to have hacks actually show up in, eg, `xscreensaver-demo`:

    GL:               exuberantbovines --root             \n\

### Creating Your Own Hacks

You'll need to create at least three files with the same base name (`$HACK`):

- the rust sourcecode (`src/bin/$HACK.rs`)
- an XML config file (`configs/$HACK.xml`)
- a manpage in Markdown format (`doc/$HACK.6.md`)

Then just add your HACK to the list in Makefile.
