-# Given a spec for the input file(s) or expected output file of a single
-# test, create a file for any string. A file is created for each literal
-# string -- not for named files. Whether a perl `string' is treated as
-# a string to be put in a file for a test or the name of an existing file
-# depends on how many references have to be traversed to get from
-# the top level variable to the actual string literal.
-# If $SPEC is a literal Perl string (not a reference), then treat $SPEC
-# as the contents of a file.
-# If $SPEC is a hash reference, then there are no inputs.
-# If $SPEC is an array reference, consider each element of the array.
-# If the element is a string reference, treat the string as the name of
-# an existing file. Otherwise, the element must be a string and is treated
-# just like a scalar $SPEC. When a file is created, its name is derived
-# from the name TEST_NAME of the corresponding test and the TYPE of file.
-# E.g., the inputs for test `3a' would be named t3a.in1 and t3a.in2, and
-# the expected output for test `7c' would be named t7c.exp.
-#
-# Also, return two lists of file names:
-# - maintainer-generated files -- names of files created by this function
-# - files named explicitly in Test.pm
