* Description

This layer adds key bindings and configuration for =sql-mode=, which manages
interactive SQL buffers and highlights a wide range of SQL dialects.

* Install
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =sql= to the existing =dotspacemacs-configuration-layers= list in this
file.

* Key bindings
