# This script makes mochitest test case templates. See
# https://developer.mozilla.org/en-US/docs/Mochitest#Test_templates
#
# It takes two arguments:
#
#   -b:     a bugnumber
#   -type:  template type. One of {html|xhtml|xul|th|chrome|chromexul}.
#           Defaults to html.
#
# For example, this command:
#
#  perl gen_template.pl -b 345876 -type xul
#
# writes a XUL test case template for bug 345876 to stdout.
