Testing local Wraith changes

...because I always forget. These are instructions for pointing to your local copy of Wraith, rather than the gem - allowing easy Wraith development.

cd ~/Desktop
gem install wraith

which wraith

# look at the value above ^^, then replace as appropriate
cd ~/.rvm/gems/ruby-2.2.1/gems/
rm -rf wraith-2.8.1/
ln -s ~/Sites/bbc/wraith/ wraith-2.8.1

cd -

Then you can wraith setup, etc.
