# During the development of 0.96, there was a --save-explain-info
# option for a brief moment that would surpress storing extra
# info in the .sconsign file(s).  At that time, this test used two
# working subdirectories to test both with and without the saved info.
# We eliminated the --save-explain-info option and the second working
# subdirectory here, but didn't go back and change all the filenames.
