First of all I'm working with epix and I’m using Mac OSX.

For those who have never heard about, epix uses Latex.

To compile, epix runs "latex" command on terminal. I'm always getting a message saying I've got memory limit.

The default engine when I run "latex" on terminal is "PDFtex". I want to change it to "Lualatex", it might solve my memory problem.

Is it possible do that?
