+# Example for simply saving it in the ~/Pictures directory.

+# Example for running custom "copying script"

+# .. where $HOME/bin/mycp could be a file with the following line:
+#   cp $3 $1/$(printf %0${2}d.png $(ls $1|wc -l))
+# .. for saving screenshots by serial numbering instead
+#
+# Example for custom copying by inline scripting (note the backslashes):
