merge
A set of doodles are combined to become one.
merge [doodlelist] <resultname>
All their connections are given to the resulting doodle on the appropriate layers. All connections between doodles in the selection become irrelevant and disappear. If a list of doodles is provided, they are merged. If no list is provided, the set of selected doodles is merged. If more than one doodle has a file the operation is cancelled. Corresponding layers of selected doodles are merged into one layer. If the merging of layers causes overlap, the user is asked to confirm the operation.
