It should be noted that the examples should be modified only
minimally to not run into problems.
Switching from from Ragnarok to guile engine (etc config) caused errors
here, also going from mysql to postgreSQL or MariaDB can cause errors.
Nevertheless, using MariaDB instead of mySQL I at least could the login
screen of the blog example on http://127.0.0.1:8085/login
Running the "hello world" still gave me errors though. All databases must
be setup and be running smoothly before artanis will work, which can be
painful with some distros.
