+**** SQL: new engine added ~sqsh~
+
+A new engine was added to support ~sqsh~ command line utility for use

+More information on ~sqsh~ can be found here: [[https://sourceforge.net/projects/sqsh/][sourceforge/sqsh]]

+To use ~sqsh~ in an *sql* =SRC_BLK= set the =:engine= like this:

+Select * From Users
