In addition to passing the file path through `expand-file-name',
tramp-style remote file names are converted to conventional (local)
file paths. The reason is that, if a tramp file name was in use in
emacs, then the shell command will be executing on the remote machine
in question. Further, by default the file name is passed through
`shell-quote-argument'.

;;; Commentary:
;; Org-Babel support for evaluating sql source code.
;;
;; SQL is somewhat unique in that there are many different engines for
;; the evaluation of sql (Mysql, PostgreSQL, etc...), so much of this
;; file will have to be implemented engine by engine.
;;
;; Also SQL evaluation generally takes place inside of a database.
;;
;; For now lets just allow a generic ':cmdline' header argument.
;;
;; TODO:
;;
;; - support for sessions
;; - add more useful header arguments (user, passwd, database, etc...)
;; - support for more engines (currently only supports mysql)
;; - what's a reasonable way to drop table data into SQL?
;;
