To install rcsh, run this command in your terminal:
$ pip install rcsh
This is the preferred method to install rcsh, as it will always install the most recent stable release.
The sources for rcsh can be downloaded from the Github repo.
You can either clone the public repository:
$ git clone git://github.com/SafPlusPlus/rcsh
Or download the tarball:
$ curl -OL https://github.com/SafPlusPlus/rcsh/tarball/master
Once you have a copy of the source, you can install it with:
$ python setup.py install
