Vision statement
<p>
This financial accounting package keeps track of a business's financial
condition. It can help by providing a standard method of keeping those
records and providing an API for other openacs packages that wish to 
use it. 
<p>
Some examples of financial data are:
<ul>
<li>Individual journal postings, showing money moving from account to
    account;
<li>Financial statements that show an abbreviated picture of the business,
    such as those you'd provide to income tax people or show to a bank so 
    you can apply for a loan; and
<li>Various ratios produced by aggregating the transactional data to 
    produce performance indicators, both in the short and the long term.
</ul>
<p>
One immediate use possibility is for ecommerce to use it to keep
track of ebusiness transactions.
