+#!/usr/bin/env python
+
+'''This spawns a sub-shell (bash) and gives the user interactive control. The
+entire shell session is logged to a file called script.log. This behaves much
+like the classic BSD command 'script'.
+
+./script.py [-a] [-c command] {logfilename}
+
+    logfilename : This is the name of the log file. Default is script.log.
+    -a : Append to log file. Default is to overwrite log file.
+    -c : spawn command. Default is to spawn the sh shell.
+
+Example:
+
+    This will start a bash shell and append to the log named my_session.log:
+
+        ./script.py -a -c bash my_session.log
