+# CL -- The main entry point of the CL.  Unlike most IRAF tasks, the CL task
+# occupies a process all by itself and takes control immediately when the task
+# is executed; the in-task interpreter never runs.  The ONENTRY procedure is
+# used to achieve this.  ONENTRY gains control from the IRAF main at process
+# startup, before the in task interpreter is entered.  The t_cl procedure is
+# not called by the interpreter as the TASK statement suggests.  The purpose
+# of the task statement is to give us an IRAF main.
