Hotloading Deps in Lein

Refactor nrepl makes it possible to hotload a dependency into lein without rebooting the repl. This is awesome but it's not super well documented.

First, make sure you have the plugin installed by adding it to the :plugins key of your lein profile. This can be done per project in project.clj, but is probably best to include in your ~/.lein/profiles.clj

Here's an example:

qemu-img convert -O vdi gnome.qcow2 gnome.vdi


#if its a raw image then:
VBoxManage convertdd opnstk.raw VBox.vdi --format VDI
