=item AM->get_account($myconfig, $form);

Populates the $form attributes accno, description, charttype, gifi_accno,
category, link, and contra with details about the account that has the id
$form->{id}.  If there are no acc_trans entries that refer to that account,
$form->{orphaned} is made true, otherwise $form->{orphaned} is set to false.

Also populates 'inventory_accno_id', 'income_accno_id', 'expense_accno_id',
'fxgain_accno_id', and 'fxloss_accno_id' with the values from defaults.

$myconfig is unused.

=item AM->save_account($myconfig, $form);

Adds or updates an account in the chart of accounts.  If $form->{id} is set,
the existing account with an id of $form->{id} is updated, otherwise a new
account is created.  The values for accno, description, charttype, gifi_accno,
category, and contra are taken directly from the $form attributes of the same
name.  The link value is generated in $form->{link} as a colon seperated list of
non-empty values from the $form attributes 'AR', 'AR_amount', 'AR_tax',
'AR_paid', 'AP', 'AP_amount', 'AP_tax', 'AP_paid', 'IC', 'IC_income', 'IC_sale',
'IC_expense', 'IC_cogs', 'IC_taxpart', and 'IC_taxservice'.

If the account is a tax account, indicated by any of IC_taxpart, IC_taxservice,
AR_tax, and AP_tax being true, and there is no entry in the tax table for the
account, a tax entry is added for the account.  If none of those tax flags are
set and this function is updating an existing account, all entries in the tax
table for the account are deleted.

$myconfig is unused.

Populates lists referred to in the form of $form->{transactions}{$type}, where
the possible values for $type are 'ar', 'ap', 'gl', 'so', and 'po', with hashes
containing details about recurring transactions of the $type variety.  These
hashes have the fields module (the frontend script that governs the transaction
type), transaction (the transaction type), invoice (true if the transaction is
an invoice), description (a field that is a customer, vendor, or in the case of
a GL transaction, an arbitrary text field), amount (the cash value of the
transaction), id (the id of the recurring transaction), reference (the
reference value for the transaction), startdate (the date the recurring
sequence started), nextdate (the date of the next occurrence of the event),
enddate (the date the sequence ends), repeat (the number of units involved in
the recurrence frequency), unit (the base recurrence unit), howmany (how many
times the event occurs), payment (whether or not the event involves a payment),
recurringemail (a colon separated list of forms to email as part of the event),
recurringprint (a colon separated list of forms to print as part of the event),
overdue (how many days until the next repetition of the event), vc (vendor,
customer, or empty), exchangerate (the exchangerate involved on the day of the
original transaction), curr (the currency of the event), and expired (if there
will be no more recurrences).

By default, these lists are sorted in order of the date of the next occurrence
of the transaction.  This order can be affected by the usual attributes used
by $form->sort_order.

recurrence series started on), nextdate (the date of the next occurrence of the
event), enddate (the date of the final occurrence of the event), repeat (the
number of units involved in a recurrence period), unit (the recurrence unit),
howmany (the total number of recurrences in the recurrence series), payment
(whether or not the transaction is associated with a payment), arid (true if an
ar event), apid (true if an ap event), overdue (number of days an ar event was
to the duedate), paid (number of days after an ar event it was paid), req (days
until the requirement date from the transdate of an oe event), oeid (true if an
oe event), customer_id (vendor id if sales order), vendor_id (vendor id if
puchase order), vc ('customer' if customer_id set, 'vendor' if vendor_id set),
invoice (true if both arid and arinvoice set or if both apid and apinvoice set),
recurringemail (colon separated list of forms and formats to be emailed),

=item AM->save_taxes($myconfig, $form);

Deletes B<all> entries from the tax table then re-inserts all taxes whose
accounts are part of the space separated list $form->{taxaccounts}.  Each
element of $form->{taxaccounts} is of the form 'chartid_I<i>' where chartid is
the id of the chart entry for the tax and I<i> is a numeric index.  The values
inserted for each tax are chart_id (from taxaccounts), rate (
form->{taxrate_I<i>} / 100), validto ($form->{validto_I<i>}), taxnumber
($form->{taxnumber_I<i>}), pass ($form->{pass_I<i>}), and taxmodule_id
($form->{taxmodule_id_I<i>}).

=item AM->backup($myconfig, $form);

Prepares and outputs a database backup of the current "dataset" using
"pg_dump -Fc".  The means of output is determined by $form->{media}, which can
be either 'file' or 'email'.  If email is the desired form of output, the email
address to send the backup to and who to claim it is from is determined by
$myconfig->{email} and $myconfig->{name}.  File output sends the backup directly
out over HTTP.
