# A utility for manual ...
# (a) validation: helping you agree that what's in .expect is right
# (b) failure replay: helping you debug one subcase, without using parent--child processes

# Usage:
# mkdir ~/uchunk-temp
# cd ~/uchunk-temp
# rm *
# ~/mywork/cfa-cc/tests/io/manipulatorsInput-uchunk.extra.sh
# ls
# diff -y all-noend.expect.txt all-noend.cpp-actual.txt | nl
