Installation Instructions

Currently, the only option is to build from source, which means you will need a Rust compiler. Head to rustup.rs and follow the instructions. By default, everything will be installed to your home directory. To install to some other directory, set the CARGO_HOME and RUSTUP_HOME environment variables to the desired installation path before running rustup. Rather will build with the default rustup settings. Rather also requires a version of the C library gsl1, and the Python package setuptools_rust which is readily availble through pip.

With the initial dependencies installed, run python setup.py install inside the source directory.

1Problems with C/C++ dependencies are the reason this is now written in Rust. I am working to remove this one because rust-gsl is not ABI-compatible with newer versions of the C library.
