Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

# Description: A program to run a simple program against every available
|
|
# pmc counter present in a system.
|
|
#
|
|
# To use:
|
|
#
|
|
# pmctest.py -p ls > /dev/null
|
|
#
|
|
# This should result in ls being run with every available counter
|
|
# and the system should neither lock up nor panic.
|
|
#
|
|
# The default is to wait after each counter is tested. Since the
|
|
# prompt would go to stdout you won't see it, just press return
|
|
# to continue or Ctrl-D to stop.
