// global-level settings somewhere other than ${user.home} and ${maven.home},
// respectively. Using a simple replacement of these patterns will allow them
// to specify the absolute path to these files in a customized components.xml
// file. Ideally, we'd do full pattern-evaluation against the sysprops, but this
// is a first step. There are several replacements below, in order to normalize
// the path character before we operate on the string as a regex input, and
// in order to avoid surprises with the File construction...
