Database installer process :

   - Yes you can run this multiple times, some people actually use 
      different dbs for different roles, i.e. mysql for the sessions,
      and oracle for user authentication. This script is _very_
      dumb and should be used with caution due to that fact. It may
      or may not blow up and delete all previous data.

   - Okay with that said, let's setup a database :
      ./create_dbs.pl   \
         --user=foo     \
         --password=bar \
         --mysql

      The account that your creating as will need to have create 
      database privileges under mysql, if the database doesn't exist.

      This doesn't create users or anything like that anymore,
      but there are example sql statements in database/(yourdb)/user.

   - But i cannot create databases, or i don't want the db called prometheus:

     That's fine, what you'll need to do is provide the db_name param
     a different value than prometheus.

      ./create_dbs.pl   \
         --user=foo     \
         --password=bar \
         --mysql        \
         --db_name=prometheus_devel
