New Library
===============

The :mod:`~assets` library is for modeling portfolios of financial instruments.
Currently, the library includes one model, :mod:`~assets.BasicBonds`.

:mod:`~assets.BasicBonds` models a portfolio of fixed rate bonds,
generates cashflows and calculates the market value of the portfolio.
:mod:`~assets.BasicBonds` uses `QuantLib`_, a third-party
open-source library for financial instrument valuation.
