    pkgsummary.py: Initial checkin for pkg summaries
    
    This module collects package test results, and ultimately outputs a
    JSON file for external consumption. Results can be at the section
    or global level.
    
    Test results are summarized by 'reporting-section' - a new
    section-level config tag.
    
    Targeted for DDPO integration of Piuparts results.

+# Piuparts summary generation module
+#
+# This module is used to create exportable section and global package testing
+# result summaries.
+#
+# The canonical location for section summaries is at
+#
+#     https://piuparts.debian.org/<section>/summary.json
+#
+# The global summary is at
+#
+#     https://piuparts.debian.org/summary.json
+#
+# Example output:
+#
+# summary.json
+# {
+#  "_comment": "Debian Piuparts Package Results - http://anonscm.debian.org/...

+# The packages are listed by source package. E.g. "unstable" here is a

+# defined in worst_flag() below. The URL is a human friendly page for
+# inspecting the results for that package/distribution.
+#
+# Binary package results are combined into source package results. The 'worst'
+# flag in the group is reported ("F" is worst overall).
