+
+    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.
