-=item _items_sections LATE SUMMARYPAGE ESCAPE EXTRA_SECTIONS FORMAT
-
-Generate section information for all items appearing on this invoice.
-This will only be called for multi-section invoices.
-
-For each line item (L<FS::cust_bill_pkg> record), this will fetch all 
-related display records (L<FS::cust_bill_pkg_display>) and organize 
-them into two groups ("early" and "late" according to whether they come 
-before or after the total), then into sections.  A subtotal is calculated 
-for each section.
-
-Section descriptions are returned in sort weight order.  Each consists 
-of a hash containing:
-
-description: the package category name, escaped
-subtotal: the total charges in that section
-tax_section: a flag indicating that the section contains only tax charges
-summarized: same as tax_section, for some reason
-sort_weight: the package category's sort weight
-
-If 'condense' is set on the display record, it also contains everything 
-returned from C<_condense_section()>, i.e. C<_condensed_foo_generator>
-coderefs to generate parts of the invoice.  This is not advised.
-
-Arguments:
-
-LATE: an arrayref to push the "late" section hashes onto.  The "early"
-group is simply returned from the method.
-
-SUMMARYPAGE: a flag indicating whether this is a summary-format invoice.
-Turning this on has the following effects:
-- Ignores display items with the 'summary' flag.
-- Combines all items into the "early" group.
-- Creates sections for all non-disabled package categories, even if they 
-have no charges on this invoice, as well as a section with no name.
-
-ESCAPE: an escape function to use for section titles.
-
-EXTRA_SECTIONS: an arrayref of additional sections to return after the 
-sorted list.  If there are any of these, section subtotals exclude 
-usage charges.
-
-FORMAT: 'latex', 'html', or 'template' (i.e. text).  Not used, but 
-passed through to C<_condense_section()>.

-=item _items_cust_bill_pkg CUST_BILL_PKGS OPTIONS
-
-Takes an arrayref of L<FS::cust_bill_pkg> objects, and returns a
-list of hashrefs describing the line items they generate on the invoice.
-
-OPTIONS may include:
-
-format: the invoice format.
-
-escape_function: the function used to escape strings.
-
-DEPRECATED? (expensive, mostly unused?)
-format_function: the function used to format CDRs.
-
-section: a hashref containing 'description'; if this is present, 
-cust_bill_pkg_display records not belonging to this section are 
-ignored.
-
-multisection: a flag indicating that this is a multisection invoice,
-which does something complicated.
-
-multilocation: a flag to display the location label for the package.
-
-Returns a list of hashrefs, each of which may contain:
-
-pkgnum, description, amount, unit_amount, quantity, _is_setup, and 
-ext_description, which is an arrayref of detail lines to show below 
-the package line.
