# Install Notes
# Before running this wrapper with Openvas make sure that:
# 1. You installed ruby version 1.9.2 and all arachni dependencies (for the gem install they are already included)
# 2. If you installed arachni 0.2.2 via the gem available on the web site, the arachni file is already on your path. Just make sure it is executable.
# 3. If you installed arachni 0.2.2 from github experimental branch, make sure that ./bin/arachni is executable and it is on your PATH.
# 4. You entered arachni path in your environmental variables: export PATH=$PATH:/path/to/your/arachni/install/bin/
