* consists in five tasks:
*
* o Check for metadata files (files.plist and props.plist),
* we only check if the file exists and its dictionary can
* be externalized and is not empty.
* o Check for missing installed files.
* o Check for target file in symlinks, so that we can check that
* they have not been modified.
* o Check the hash for all installed files, except
* configuration files (which is expected if they are modified).
* o Check for missing run time dependencies.
