Comment 80 for bug 388145

The account_anglo_saxon module does change the behavior of the account module. (from technical point of view it inherit object account)
Then the behavior of Stock input account and Stock output account is modified. Those act WITH account_anglo_saxon as the so called Interim accounts.
When the goods are received or send these interim accounts are used for the financial transaction and with the second step when invoice is set from draft to active these interim accounts will be contra booked and the amount is transferred then to the debtor or creditor.

A small description is available into the module and readable when installing. Perhaps we have to extent this more.
I will extent doc.openerp.com as soon as the module is listed here. Still it is not added to the docs.
