It always takes longer than you think. In the FAQ list for the AScopy home page I stated that for a version 1.0.0 to arrive AScopy should be (among other things) be able to exclude files and directories. This means that I can safely update a site for which I still have files open, e.g. using ViM.

Normally that would cause AScopy to detect the ViM swap-files as new files, but now they can be excluded in the .ascopyrc file like this:

exclude .*.swp

And that is all there is to it. The new version can be downloaded here.
