This library contains hledger's core functionality. It is used by most hledger* packages so that they support the same command line options, file formats, reports, etc. hledger is a robust, cross-platform set of tools for tracking money, time, or any other commodity, using double-entry accounting and a simple, editable file format, with command-line, terminal and web interfaces. It is a Haskell rewrite of Ledger, and one of the leading implementations of Plain Text Accounting.
