This pair of scripts makes it easy to package a large, complex linked set of objects into a single package, and then build the entire complex at once. Basically, it works by choosing one object to be the "base", and then putting a copy of all the other objects into base's inventory after recording their relative position and rotation. The instructions expect intermediate building skills, and are in the scripts themselves, so they won't be repeated here.
The first script is also a decent example of using a menu, and of parsing chat input.

// Script Purpose & Use
// Functions are dependent on the "component script"
//
// QUICK USE:
// - Drop this script in the Base.
// - Drop the "Component" Script in each building part.
// - Touch your Base, and choose RECORD
// - Take all building parts into inventory
// - Drag building parts from inventory into Base Prim
// - Touch your base and choose BUILD
//
// OTHER COMMANDS from the Touch menu
// - To reposition, move/rotate Base Prim choose POSITION
// - To lock into position (removes scripts) choose DONE
// - To delete building pieces: choose CLEAN
