local dev settings for drupal

_notes

These are not prod safe settings. Performance is not suitable for
general use.

Security or heavy performance things are commented out. You may want to 
enable them manually.

To use, place these files in your sites/default/settings.php
should include the local.settings.php (if it exists). Then exclude
local.settings.* files in your .gitignore.

Thanks @dpi.
