Good to know, I haven't used it. I haven't really done much with scripting in Lisp (I think I'm actually still within the first 10k written lines of it, for whatever that metric is worth) so for filesystem and OS tasks I haven't gone much beyond the standard and some sb-ext functions. I don't really have a need or desire to move from bash or python for scripting; it's the larger programs that make me wish I had Lisp around when I don't.
