 Partisan may be defined as a strong supporter of a cause, party or person.
 We need not limit ourselves to the two major political parties in the US today.
 
 Let us consider:
 
+```sh
 ./cable1 Cooper Mac PC
+```
 
 Simon works for Apple, so would would expect Mac.  :-)
 Landon is a long time Mac user:
 
+```sh
 ./cable1 Noll Mac PC
+```
 
 That works too!.  Now Leo brings PCs to the IOCCC judging for cross-platform
 testing:
 
+```sh
 ./cable1 Broukhis Mac PC
+```
 
 We can test other people.  The late Steve Jobs:
 
+```sh
 ./cable1 Jobs Mac PC
+```
 
 That works!  How about Bill?
 
+```sh
 ./cable1 Gates Mac PC
+```
 
 A PC guy as expected.  What about that other Steve?
 
+```sh
 ./cable1 Ballmer Mac PC
+```
 
 Humm .. maybe there is a hidden reason he is leaving the late Micro$oft? :-)
