# This test compares "known good" output with various settings against output

# with the current code. It's brittle by nature, but this is probably the
|
|
# "best" approach possible.

|
# Notes:
|
|
# * options passed to this script (such as -v) are ignored, as they would change
|
|
# the output and break the test
|
|
# * the number of asterisks after a "banner" differs depending on the number of
|
|
# columns on the TTY, so we must adjust the columns for the current session
|
|
# for consistency
