Install the package (as above):
curl -sS https://getcomposer.org/installer | php
php composer.phar require jamiehannaford/doc-validator:1.0.0
Execute the binary:
./vendor/bin/openstack
Check the process is running:
ps aux | grep php
The process takes around 10 minutes to complete; the majority of the time is spent by wget downloading the files. Once this is done, you can view the log file:
cat ./vendor/jamiehannaford/doc-validator/log/docs.openstack.org.log
