Helper method for installing Virtuoso ServerSource:
Installation helper for Mac and Windows machines. By default,
method will download and launch the official
for your platform, running the standard drag-n-drop installer or
interactive dialog. Setting
ask = FALSE will allow the installer
to run entirely unsupervised, which is suitable for use in scripts.
Mac users can alternatively opt to install Virtuoso through HomeBrew
use_brew=TRUE. Linux users should simply install the
virtuoso-opensource package (e.g. in debian & ubuntu) using the
package manager or by contacting your system administrator.
Should we ask user for interactive installation?
Should we use homebrew to install? (MacOS only)
if(has_virtuoso()) vos_install() #> Virtuoso is already installed.
