-
-    Extracts the 4 metadataitems needed (name, version, pyversion, arch) from
-    the installer filename and the name of the egg-info directory embedded in
-    the zipfile (if any).
-
-    The egginfo filename has the format::
-
-        name-ver(-pyver)(-arch).egg-info
-
-    The installer filename has the format::
-
-        name-ver.arch(-pyver).exe
-
-    Some things to note:
-
-    1. The installer filename is not definitive. An installer can be renamed
-       and work perfectly well as an installer. So more reliable data should
-       be used whenever possible.
-    2. The egg-info data should be preferred for the name and version, because
-       these come straight from the distutils metadata, and are mandatory.
-    3. The pyver from the egg-info data should be ignored, as it is
-       constructed from the version of Python used to build the installer,
-       which is irrelevant - the installer filename is correct here (even to
-       the point that when it's not there, any version is implied).
-    4. The architecture must be taken from the installer filename, as it is
-       not included in the egg-info data.
-    5. Architecture-neutral installers still have an architecture because the
-       installer format itself (being executable) is architecture-specific. We
-       should therefore ignore the architecture if the content is pure-python.
