// 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.
