+;
+; CHANGE-LOG:
+; 1.00 - initial release
+; 1.01 - fixed the problem with a remaining copy of the selection
+; 1.02 - some code cleanup, no real changes
+; 1.03 - can't call gimp-drawable-edit-fill until layer is added to image!
+; 1.04
+; 1.05 - replaced deprecated function calls with new ones for 2.8

+;
+;
+; Adds a drop-shadow of the current selection or alpha-channel.
+;
+; This script is derived from my script add-shadow, which has become
+; obsolete now. Thanks to Andrew Donkin (ard@cs.waikato.ac.nz) for his
+; idea to add alpha-support to add-shadow.
