hledger development
===================

**Techie intro**

hledger_ is a remix, in haskell_, of John Wiegley's excellent ledger_ accounting tool.
It reads a plain text journal_ or timelog_ file describing your transactions
and displays reports via command line, curses or web interfaces.

The hledger project aims to produce:

- a practical, accessible, dependable tool for end users
- a useful library and toolbox for finance-minded haskell programmers
- a successful, time-and-money-solvent project within a thriving ecosystem of financial software projects.

hledger is free software by `Simon Michael`_ & `co.`_, released under GNU GPLv3.

- John Wiegley's ledger_ inspired hledger, and we try to stay compatible. You can often use both tools on the same journal file.
- Uwe Hollerbach's umm_ is another haskell tool inspired by h/ledger.
- Tim Docker's ledger-reports_ uses hledger as a library to generate `html reports`_. 
- I have a few older bits and pieces `here <http://joyful.com/Ledger>`_.
