Installation Raven


To install and use Raven,

# Make sure your Chez Scheme compiler named "scheme". If not,

# cd /usr/local/bin
# cp chez scheme

The above paths may vary depending on your Linux distribution.

# Make sure your system can use the command "curl".

This command comes with Mac OS X and most Linux distributions, but if you do not, install it yourself to make sure Raven's network download function is working.
