directory tree

Hi all,
The following is a script for displaying directory tree.

D=${1:-`pwd`}
(cd $D; pwd)
find $D -type d -print | sort |
sed -e "s,^$D,,"\
-e "/^$/d"\
-e "s,[^/]*/\([^/]*\)$,\:-----\1,"\
-e "s,[^/]*/,: ,g" | more
exit 0

I am trying to understand the above script.But i am not able to understand the following 2 lines

-e "s,[^/]*/\([^/]*\)$,\:-----\1,"\
-e "s,[^/]*/,: ,g" | more

can any body pls tell me how the above two lines works.
