A processing list is a list of
description files and module files to be processed, as well as OS commands to be executed. A processing list can also contain other processing lists. In addition, options can be specified.The entries in a processing list are processed by VMAKE from top to bottom. All of the listed files, as well as any other files listed as links, are first checked down to the lowest level to determine whether they have been changed with respect to a target created previously. Only if this is the case does VMAKE recreate (update) the targets.
