Narrative:

I received a release from the radar controller for a C510 and cleared him for takeoff. A few seconds later; the radar controller called and requested a point-out on an air carrier aircraft inbound to dal. I just automatically approved the point-out; not thinking about the departure. I did not realize until the C510 had become airborne that the radar controller had allowed the air carrier aircraft to descend to 2;000 about 2 miles south of the runway; the same altitude that the C510 was climbing to. I instructed the C510 to start his turn to the northeast as early as possible. When the C510 tagged up on the radar; he was 2 miles from the air carrier aircraft; climbing to 2;000 on opposite courses. The radar controller should not have requested a point-out and allowed the aircraft to descend to the same altitude that the aircraft he had released for departure was climbing to. I should have denied the point-out and reminded the radar controller of the aircraft on departure roll.
