Enable the CRS rules files you want to use by creating symlinks under the
     "activated_rules" directory location.  You will want to create symlinks for the
     following:

     1) The main modsecurity_crs_10_setup.conf file
     2) Any rules from the base_rules directory
     3) Any remaining rules from the optional_rules, slr_rules or experimental_rules directories.
