# uncombine.pl : Break up the combined performance run output file into a file per URL
#
# When viewer or mozilla are run and provided a command line argument of '-f urlfile.txt'
# then the file 'urlfile.txt' is read and each line is expected to be a URL. The browser
# then cycles through each url and loads it, waiting for the load to end or a safety
# timeout to occur. In eaiter case the next url is loaded until there are no more and then
# the browser exits. The output from the run (stdout) is captured to a file which then
# contains all of the performance output we need to build charts of performance numbers
# (see average2.pl, along with header.pl and footer.pl).
#
# ASSUMES file urls are pathed as: file:///S|/Mozilla/Tools/ProfTools/WebSites/URL/FILE
# or if an http URL: http://URL/FILE
# Normally it is expected that local files will be used, however if we should use http
# URLs they can be processed (have not tested to date...)
#
# For file urls, the websites tree is assumed to be the one committed to cvs. Installed
# files will be at s:\mozilla\tools\perftools\websites\url\file
# If you have the files in a different location, adjust the part that extracts the url
# (most likely the index into the tokens will change. Search for SENSITIVE in the script)
