# Changelog:
# 2009-12-17  fix: small glitch in toxml / toprettyxml methods (xml declaration
#                  wasn't replaced when a different encodig than UTF-8 was used)
#             chg: catch xml.parsers.expat.ExpatError and re-raise as
#                  ManifestXMLParseError
#             chg: support initialize option in parse method also
#
# 2009-12-13  fix: fixed os import
#             fix: skip invalid / empty dependent assemblies
#
# 2009-08-21  fix: Corrected assembly searching sequence for localized
#                  assemblies
#             fix: Allow assemblies with no dependent files
#
# 2009-07-31  chg: Find private assemblies even if unversioned
#             add: Manifest.same_id method to check if two manifests have the
#                  same assemblyIdentity
#
# 2009-07-30  fix: Potential failure in File.calc_hash method if hash
#                  algorythm not supported
#             add: Publisher configuration (policy) support when searching for
#                  assembly files
#             fix: Private assemblies are now actually found if present (and no
#                  shared assembly exists)
#             add: Python 2.3 compatibility (oldest version supported by
#                  pyinstaller)
#
# 2009-07-28  chg: Code cleanup, removed a bit of redundancy
#             add: silent mode (set silent attribute on module)
#             chg: Do not print messages in silent mode
#
# 2009-06-18  chg: Use glob instead of regular expression in Manifest.find_files
#
# 2009-05-04  fix: Don't fail if manifest has empty description
#             fix: Manifests created by the toxml, toprettyxml, writexml or
#                  writeprettyxml methods are now correctly recognized by
#                  Windows, which expects the XML declaration to be ordered
#                  version-encoding-standalone (standalone being optional)
#             add: 'encoding' keyword argument in toxml, toprettyxml, writexml
#                  and writeprettyxml methods
#             chg: UpdateManifestResourcesFromXML and
#                  UpdateManifestResourcesFromXMLFile: set resource name
#                  depending on file type ie. exe or dll
#             fix: typo in __main__: UpdateManifestResourcesFromDataFile
#                  should have been UpdateManifestResourcesFromXMLFile

        IMPORTANT NOTE: On some Windows systems, the dependency listed in the manifest
        will not actually be present, and finding its files will fail. This is because
        a newer version of the dependency is installed, and the manifest's dependency
        is being redirected to a newer version. To properly bundle the newer version of
        the assembly, you need to find the newer version by setting
        ignore_policies=False, and then either create a .config file for each bundled
        assembly, or modify each bundled assembly to point to the newer version.
