how debits & credits to the Account should be treated and displayed.

@item A parent and child Account Group.
The parent and child of an Account are Account Groups
(@pxref{Account Groups}). Account Groups are used to
connect Accounts together into an Account hierarchy.
If the parent Account Group is not present, the Account
is at the top level of the hierarchy. If the child
Account Group is not present, the Account has no
children.

@subsection Account Types
@tindex GNCAccountType
Account Types are defined by the @code{GNCAccountType} enumeration.
Possible values are:
@table @code
@item BAD_TYPE, NO_TYPE
Both of these values indicate an illegal Account type.
@item BANK
Denotes a savings or checking account held at a bank.
Such an account is often interest bearing.
@item CASH
Denotes a shoe-box or pillowcase stuffed with cash. In other
words, actual currency held by the user.
@item CREDIT
Denotes credit card accounts.
@item ASSET
Denotes a generic asset account.
@item LIABILITY
Denotes a generic liability account.
@item STOCK
A stock account containing stock shares.
@item MUTUAL
A mutual fund account containing fund shares.
@item CURRENCY
Denotes a currency trading account. In many ways, a currency trading
account is like a stock trading account, where both quantities
and prices are set. However, generally both currency and security
are national currencies.
@item INCOME
Denotes an income account. The GnuCash financial model does not
use 'categories'. Actual accounts are used instead.
@item EXPENSE
Denotes an expense account.
@item EQUITY = 10,

@deftypefun void xaccAccountDestroy (Account * @var{account})

this function.
@end deftypefun
@deftypefun void xaccAccountBeginEdit (Account * @var{account})

provide a two-phase-commit wrapper for account updates
much in the same way as @var{xaccTransBeginEdit} and
@var{xaccTransCommitEdit} do for Transactions.

account returned by @code{xaccMallocAccount}.
