useage: $0 [-f] [-m "description"] [-p "prefix"] [-d destdir] file1.ext file2.ext ...

File given files into $destdir (can be overridden with -d), and rename
them into the following naming scheme:

prefix/$date description1.ext
prefix/$date description2.ext
prefix/$date description3.ext

Here prefix is the name of an optional subdirectory (defaults to "").
If the optional description is not given then this naming scheme is
used:

prefix/$date file1.ext
prefix/$date file2.ext
prefix/$date file3.ext

The moving and renaming will only be performed if the "safety switch"
-f is given.
