+;; Org-Babel support for evaluating ledger entries.

+;; This differs from most standard languages in that

+;; 1) there is no such thing as a "session" in ledger
+;;
+;; 2) we are generally only going to return output from the ledger program
+;;
+;; 3) we are adding the "cmdline" header argument
+;;
+;; 4) there are no variables
