newclude – Reimplemented \include system for LaTeX

A LaTeX pack­age pro­vid­ing a back­wards-com­pat­i­ble reim­ple­men­ta­tion of \in­clude and \in­cludeonly. The prin­ci­pal new fea­tures are:
(1) the re­stric­tion that \clearpages must sur­round an in­cluded file is re­moved, (2) the re­stric­tion that \in­cludes can­not be nested is re­moved, and (3) the pro­vi­sion of hooks to be ex­e­cuted be­fore and af­ter the con­tents of an in­cluded file.
New­clude ac­com­plishes the first two by us­ing a sin­gle .aux file in­stead of many. New­clude also pro­vides the ex­per­i­men­tal func­tion­al­ity of the un­sup­ported pack­age in­cludex, which al­lows you to in­clude par­tial con­tents of in­de­pen­dent LaTeX files that can also be pro­cessed on their own (that is, files that con­tain \doc­u­ment­class, \be­gin{doc­u­ment}, etc.).
