Physical Sections Rules
Each Physical Section is made up of one or more Section Rule.
The All Other Pages rule is simple; it collects all pages not used by either of the other rules (and as such only one section may use this rule). This rule is specified directly in the rules editor.
For other sections, there are 4 types of sections rules which are defined in the physical sections rule editor (note rule as opposed to rules) :
Range of Pages : Includes pages from a page number to another, inclusively. Because physical sections are meant to emulate the printing world, this is the least useful type of rule. You can specify if the pages will be counted from the back of the book, rather than from the front.
Pages at the Front : Includes a number of pages at the front. Usually combined with Pages at the Back, either for end pages, tip-in pages, or saddle-stitched diaries.
Pages at the Back : Includes a number of pages at the back. Usually combined with Pages at the Front, either for end pages, tip-in pages, or saddle-stitched diaries.
Complete Signature : Includes all the pages from a given signature. You can specify if the signatures will be counted from the back of the book, rather than from the front.
