# Calling the post-processor with file-upload. Assumes the username
# and password are in ~/.curl-w3.org (user = USER:PASS)
#
# To set a date other than today, use: make date=YYYY-MM-DD
#
# "cdate" is an alias for "date": "make cdate=YYYY-MM-DD" works, too.
#
# To set the status, modify one of the "this version" URLs:
# http://www.w3.org/TR/[YEAR]/CR-[SHORTNAME]-[CDATE]/
# Or set that URL to [VERSION] and call Make as: make status=CR
#
#
# Possible other options to add to the curl command below:
# -F ids=on
# -F omitdchtml=on
# e.g., like this: make opts="-F ids=on -F omitdchtml=on"
