// This file provides a utility for merging Microsoft .manifest files.  These
// files are xml documents which contain meta-information about applications,
// such as whether or not admin access is required, system compatibility,
// versions, etc.  Part of the linking process of an executable may require
// merging several of these .manifest files using a tree-merge following
// specific rules.  Unfortunately, these rules are not documented well
// anywhere.  However, a careful investigation of the behavior of the original
// Microsoft Manifest Tool (mt.exe) revealed the rules of this merge.  As the
// saying goes, code is the best documentation, so please look below if you are
// interested in the exact merging requirements.
