+# script. It then runs sh -n to see if bash can determine if there are obvious
+# parsing errors. It does have a bug in that bash -n does not take into 
+# account someone may program an unconditional exit and then include man page
+# generation information. It also fails to notice the exec command. When you
+# run across files that do either of the above, add it to the KNOWN_BAD list.
