Description:
 hledger-interest is a small command-line utility based on Simon
 Michael's hleder library. Its purpose is to compute interest for a
 given ledger account. Using command line flags, the program can be
 configured to use various schemes for day-counting, such as act\/act,
 30\/360, 30E\/360, and 30\/360isda. Furthermore, it supports a (small)
 number of interest schemes, i.e. annual interest with a fixed rate and
 the scheme mandated by the German BGB288 (Basiszins fuer
 Verbrauchergeschaefte). Extending support for other schemes is fairly
 easy, but currently requires changes to the source code.
 .
 As an example, consider the following loan, stored in a file called
 @test.ledger@:
 .
 > 2008/09/26 Loan
 >     Assets:Bank          EUR 10000.00
 >     Liabilities:Bank
 >
 > 2008/11/27 Payment
 >     Assets:Bank          EUR -3771.12
 >     Liabilities:Bank
 >
 > 2009/05/03 Payment
 >     Assets:Bank          EUR -1200.00
 >     Liabilities:Bank
 >
 > 2010/12/10 Payment
 >     Assets:Bank          EUR -3700.00
 >     Liabilities:Bank
 .
 Suppose that loan earns 5% interest per year, and payments amortize
 interest before amortizing the principal claim, then the resulting
 ledger would look like this:
 .
 > $ hledger-interest --file=test.ledger --source=Expenses:Interest --target=Liabilities:Bank --30-360 --annual=0.05 Liabilities:Bank
 > 2008/09/26 Loan
 >     Assets:Bank              EUR  10000.00
 >     Liabilities:Bank
 >
 > 2008/11/27 Payment
 >     Assets:Bank              EUR  -3771.12
 >     Liabilities:Bank
 >
 > 2008/11/27 5.00% interest for EUR -10000.00 over 61 days
 >     Liabilities:Bank         EUR    -84.72
 >     Expenses:Interest
 >
 > 2008/12/31 5.00% interest for EUR -6313.60 over 34 days
 >     Liabilities:Bank         EUR    -29.81
 >     Expenses:Interest
 >
 > 2009/05/03 Payment
 >     Assets:Bank              EUR  -1200.00
 >     Liabilities:Bank
 >
 > 2009/05/03 5.00% interest for EUR -6343.42 over 123 days
 >     Liabilities:Bank         EUR   -108.37
 >     Expenses:Interest
 >
 > 2009/12/31 5.00% interest for EUR -5251.78 over 238 days

 >
 > 2010/12/10 Payment
 >     Assets:Bank              EUR  -3700.00
 >     Liabilities:Bank
 >
 > 2010/12/10 5.00% interest for EUR -5425.38 over 340 days
 >     Liabilities:Bank         EUR   -256.20
 >     Expenses:Interest
