-    I've modified a (modified) version of Bill Rosenblatt's ksh debugger
-    to work with bash-2.0.  Does ORA have any problem with me distributing
-    it with bash-2.0?
-    
-That's great!
-
-Go ahead and circulate it; in fact, we should probably grab it and
-stick it in our ftp archive, and put a reference to it in the book.
-(Too late to actually discuss the thing, at least for this edition).

+    $scriptName [-t timeout] [-i interval] [-d delay] command
+    Execute a command with a time-out.
+    Upon time-out expiration SIGTERM (15) is sent to the process. If SIGTERM
+    signal is blocked, then the subsequent SIGKILL (9) terminates it.
+
+    -t timeout
+        Number of seconds to wait for command completion.
+        Default value: $DEFAULT_TIMEOUT seconds.
+
+    -i interval
+        Interval between checks if the process is still alive.
+        Positive integer, default value: $DEFAULT_INTERVAL seconds.
+
+    -d delay
+        Delay between posting the SIGTERM signal and destroying the
+        process by SIGKILL. Default value: $DEFAULT_DELAY seconds.
+
+As of today, Bash does not support floating point arithmetic (sleep does),
+therefore all delay/time values must be integers.
