This is hledger's command-line interface. Its basic function is to read a plain text file describing financial transactions and produce useful reports. hledger is a computer program for easily tracking money, time, or other commodities, on unix, mac and windows (and web-capable mobile devices, to some extent). It is first a command-line tool, but there are also terminal and web interfaces, and a Haskell library (http://hackage.haskell.org/package/hledger-lib) for building your own programs and scripts (hledger is written in Haskell). hledger was inspired by and is largely compatible with Ledger. hledger is free software available under the GNU General Public License v3+. hledger aims to help both computer experts and regular folks to gain clarity and control in their finances and time management, but currently it is a bit more suited to techies.
