#smoove_lists source target

#takes the contents one level deep in the directories in source
#and stuffs them into similarly named directory in target.
#the directoy under target is named after the last directory
#component in each source directory name.
#here's an example:
#   smoovelists  ~/notes_pending  ~/list_archive
#would move all the files in the directories under notes_pending into
#similar directories under list_archive.
#so, a file ~/notes_pending/foolio/moopter.txt would get moved over to
#a directory called ~/list_archive/moopter.txt
#
#this is useful for coalescing a subset of some to-do items that are under
#directories in a temporary folder into the main archive of to-dos.
#otherwise one must do some manual labor to collapse the directories into
#the right places.
#it only supports one level deep of directories currently because that's
#the most common usage.
