I'm using Julia to build a imagemagick command (for a complicated gif). I'm using a for loop to build the many frames for the gif. This means I end up with an Array of Cmds where the first element is some header (i.e. `convert -delay 1 -size $(w)x$h xc:black -antialias`), then come the frames, and last some closing stuff. I wish I then could just join the commands and run it. But join doesn't work on the Cmd type.
How can I build a Cmd from many parts? Thanks!
