+    First, try to parse a file named "/etc/lsb-release".  If it exists, and

+    the strings parsed from that file.
+
+    If that doesn't work, then invoke platform.dist().
+
+    If that doesn't work, then try to execute "lsb_release", as standardized in
+    2001:

+    The current version of the standard is here:

+
+    that lsb_release emitted, as strings.

+    Returns a tuple (distname,version). Distname is what LSB calls a
+    "distributor id", e.g. "Ubuntu".  Version is what LSB calls a "release",
+    e.g. "8.04".
+
+    A version of this has been submitted to python as a patch for the standard
+    library module "platform":
