     "Ledger is a powerful, double-entry accounting system that is
accessed from the UNIX command-line.  This may put off some users, since
there is no flashy UI, but for those who want unparalleled reporting
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.")

    (description
     "Ledger is a powerful, double-entry accounting system that is
accessed from the UNIX command-line.  This may put off some users, since
there is no flashy UI, but for those who want unparalleled reporting
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.

This package provides the Emacs mode.")

sends VAT declarations to Germany's fiscal authorities.

Currently it is *not* possible to send returns that are due annually
(especially the income tax return) since the fiscal authority doesn't
allow doing that off the ERiC library (which is proprietary however).
It's not clear at the moment whether one day it will be possible to
do so.")
