-                                    point program.  Such a call point program

+    call_point                      The call point program to be called for each plug-in package (e.g.
+                                    post_boot).  This name should not include the "cp_" prefix.

+                                    non-zero return code.  For example, if this value equals 0x00000200, it

+                                    be counted as a failure.
+    stop_on_plug_in_failure         If this parameter is set to 1, this program will stop and return non-zero
+                                    if the call point program from any plug-in directory fails.  Conversely,
+                                    if it is set to false, this program will run the call point program from
+                                    each and every plug-in directory regardless of their return values.
+                                    Typical example cases where you'd want to run all plug-in call points
+                                    regardless of success or failure would be "cleanup" or "ffdc" call points.
+    stop_on_non_zero_rc             If this parm is set to 1 and a plug-in call point program returns a valid
+                                    non-zero return code (see "shell_rc" parm above), this program will stop
+                                    processing and return 0 (success).  Since this constitutes a successful
+                                    exit, this would normally be used where the caller wishes to stop
+                                    processing if one of the plug-in directory call point programs returns a
+                                    special value indicating that some special case has been found.  An
+                                    example might be in calling some kind of "check_errl" call point program.
+                                    Such a call point program might return a 2 (i.e. 0x00000200) to indicate
+                                    that a given error log entry was found in an "ignore" list and is
+                                    therefore to be ignored.  That being the case, no other "check_errl" call
+                                    point program would need to be called.
+    release_type                    The type of release being tested (e.g. "obmc", "op", "fips").  This

+    quiet                           If quiet is set to 1, this function will NOT write status messages to
