[Haskell] ANN: hledger 0.21

[Simon Michael]

I'm pleased to announce hledger and hledger-web 0.21!

hledger is a command-line tool and haskell library for tracking
financial transactions, which are stored in a human-readable plain
text format. In addition to reporting, it can also help you record new
transactions, or convert CSV data from your bank. Add-on packages
include hledger-web (providing a web interface), hledger-irr and
hledger-interest.

hledger is inspired by and compatible with John Wiegley's Ledger. For
more, see http://hledger.org .

Install it:

cabal update; cabal install hledger [hledger-web]
