# Description:
# YARP - Yet Another Recipe Parser
# This tool parses Raptor logs looking for failures, and writes a CSV file of the results
#
# Usage:
# perl yarp.pl <logfile> <csvfile>
#
# Notes:
# Currently it won't tell you any info about why it fails, with the exception of arm licence issues.
# It also uses a lot of memory, so while there is a subroutine for doing multiple files, it's not used, and is out of date.
# Writing output to a file is hacked in, so it's not too pretty.
