Add a Ruby wrapper library around the libseccomp library. Seccomp is used to restrict the syscalls a program can make. See comments in app/logical/seccomp.rb for further details. This is not used for anything yet. It's simply adding part of the sandboxing infrastructure for later use.
Config
This directory contains configuration files for Danbooru.
To configure your Danbooru instance, copy danbooru_default_config.rb to danbooru_local_config.rb and edit it. See danbooru_default_config.rb for details.
The only file here that end users need to be concerned about is danbooru_default_config.rb. The rest of the files here are internal Rails-related configuration files that end users shouldn't need to edit.
