-#!/usr/bin/python3
-#
-# Python script to parse dependency export CSV from Understand. It detects
-# these common architectural problems:
-# * Common code depends on hardware headers
-# * HAL unit depends directly on another HAL unit. The dependency should
-#   always be via HAL interface.
-# * Two units have a circular dependency.
-#
-# Usage:
-#
-# understand_deps_analyze.py <deps_export.csv
-#
-# Notice that the CSV export has to be made by:
-# * Create architecture XML with nvgpu_arch.py (command understand)
-# * Create nvgpu project in Understand and add nvgpu code, both common and qnx
-#   directories
-# * Import architecture XML to Understand
-# * View Graphs->Dependency graphs->By nvgpu (nvgpu probably comes from the
-#   name of the architecture .xml file
-# * Create arch dependendency report:
-#   * Reports->Dependency->Architecture Dependencies->Export CSV
-#   * Choose nvgpu as "Select an architecture to analyze"
