-# To use this script you will need to have exported data using either the
-# export-to-sqlite.py or the export-to-postgresql.py script. Refer to those
-# scripts for details.
-#
-# Following on from the example in the export scripts, a
-# call-graph can be displayed for the pt_example database like this:
-#
-# python tools/perf/scripts/python/call-graph-from-sql.py pt_example
-#
-# Note that for PostgreSQL, this script supports connecting to remote databases
-# by setting hostname, port, username, password, and dbname e.g.
-#
-# python tools/perf/scripts/python/call-graph-from-sql.py "hostname=myhost username=myuser password=mypassword dbname=pt_example"
-#
-# The result is a GUI window with a tree representing a context-sensitive
-# call-graph. Expanding a couple of levels of the tree and adjusting column
-# widths to suit will display something like:
-#
-# Call Graph: pt_example
-# Call Path Object Count Time(ns) Time(%) Branch Count Branch Count(%)
-# v- ls
-# v- 2638:2638
-# v- _start ld-2.19.so 1 10074071 100.0 211135 100.0

-# Points to note:
-# The top level is a command name (comm)
-# The next level is a thread (pid:tid)
-# Subsequent levels are functions
-# 'Count' is the number of calls
-# 'Time' is the elapsed time until the function returns
-# Percentages are relative to the level above
-# 'Branch Count' is the total number of branches for that function and all
-# functions that it calls
