With this lineup, one must know the exact order of the subjects.
Having more than two subjects and lining them correctly will get
tedious, time consuming, and make script construction more involved.

The problem I'm up against is contingent on another issue --
insensitive casing. Sed does a great job of finding things (without
any set order), but is heavily reliant on casing. Grep has the "-i"
option that rules out all case contingencies.
I know I could pipe input through tr '[:upper:]' '[:lower:]' for
sed, but one more command makes it lengthy and it also distorts the
output -- making it unreliable.
Note: Detailed Document(s) and Sample(s) are more than welcome!
