# There are five different things we need to examine:
#
# 1. That the autogen internal string.
# 2. What we expect that string to contain.
# 3. What is generated as the "C" representation
# 4. What is generated for raw shell strings
# 5. What is generated for "cooked" shell strings
#
# We will compare all these things by generating a C program that
# will test the various strings and a shell script to invoke the
# program with the two shell string formats for arguments.
# The program will also write out the expected string value.
# That value will be compared with what autogen wrote out
# as its internal value.
#
# All this stuff must be generated carefully.
# Specifically, the '${testname}' expressions need to
# be expanded in certain parts of the output file.
# In those areas, the eof marker must *not* be quoted.
# In other places (e.g., where defining the strings),
# rather than hassle with understanding shell quoting rules,
# instead we *will* quote the EOF marker to avoid
# any shell interpretation at all!!
