I've tried installing conque using vundle but not had any success so I'm trying to install manually using the instructions online:
Open the .vba file with Vim and run the following commands:
:so %
:q
How can I automate installing vim?
This appears to have worked, so I'm documenting it in case it is useful for others:
$ vim 'https://conque.googlecode.com/files/conque_2.3.vmb' -c ':so % | q'
