+# sfsum.py:  A script for parsing XML data exported from
+#            SourceForge projects.
+#
+# Right now, this is hard-coded to generate a summary of open bugs.
+#
+# XML data for SourceForge project is available for download by project
+# administrators.  Because it's intended for backup purposes, you have
+# to slurp the whole set of data, including info about all of the closed
+# items, the feature requests, etc., so it can get big.
+#
+# You can do this by hand (if you're an administrator) with a URL like
+# this (where 30337 is the group_id for SCons):
+#
+#       http://sourceforge.net/export/xml_export.php?group_id=30337
+#
+# They also have a Perl script, called xml_export, available as part
+# of a set of utilities called "adocman" which automate dealing with
+# SourceForge document management from the command line.  "adocman"
+# is available at:
+#
+#       https://sourceforge.net/projects/sitedocs/

+    each other in the Arifact object we create.
+
