Cool project!

What about a syntax like:

  Copy all files recursively:

    xcv .

  Cut all files recursively:

    xcv -x .

  List all files which will be pasted:

    xcv -l

  Paste all copied files elsewhere:

    xcv -v /elsewhere

It's just that most people will want to do those things by default, and remembering "xcv c -R ." is a bit more mental effort than "xcv ." But maybe that's just a personal preference.
