# Take an input file which contains a header of the form:
# /* Template: [template name] */
# followed by a blank line, then one or more sections of the form:
# /*
# [Error message|‘No error’]
# */
# {
# [Code]
# }
#
# Sections are separated by ‘/*’ on a line of its own. The code must not contain
# C-style comments (‘/* … */’), but can contain C++-style ones (‘// …’).
#
# The wrapper script takes each section and wraps the code in a main() function
# with some standard variables and reference count handling provided by the
# named template. It then compiles
# the code using Clang with Tartan, and checks the compiler output against
# the expected error message. If the expected error message is ‘No error’ it
# asserts there’s no error.
