+access to their data there are few alternatives.
+
+Ledger uses text files for input.  It reads the files and generates
+reports; there is no other database or stored state.  To use Ledger,
+you create a file of your account names and transactions, run from the
+command line with some options to specify input and requested reports, and
+get output.  The output is generally plain text, though you could generate
+a graph or html instead.  Ledger is simple in concept, surprisingly rich
+in ability, and easy to use.")
