The Ledger accounting system is a powerful (but not very easy to adopt) software tool for double-entry bookkeeping. It can be used for far more than just basic finances: tracking billable hours, calculating taxes and tithes, reporting on the asset class balance of your investment portfolio… almost anything you can think of — if you can figure out how to do it.
Most of the information I could find just presented a basic overview of the simplest possible use of the tool. The official documentation, on the other hand, is very comprehensive, but it's like being given a pile of logs and some nails when you're trying to find out how to build a house.
I therefore will be writing up a series of posts on “Ledger Practices”, describing how I actually use the system for intermediate-complexity personal accounting. These should be “recipes” for solving real problems or answering real questions using ledger.
