Project Summary
Ledger is a powerful, double-entry accounting system that is accessed from the UNIX command-line. This may put off some users, as there is no flashy UI, but for those who want unparalleled reporting access to their data, there really is no alternative.
Here are some of the features of Ledger which set it apart from other accounting systems:
* Ledger never creates or modifies your data.
* Ledger is 100% currency-agnostic.
* Ledger is international (UTF-8, ISO format dates, US or European decimal formats).
* Ledger uses a simple set of base commands which can be extended in countless ways.
