## This PKGBUILD creates an Arch Linux package for the proprietary MATLAB application.
## In order to build the package the user must supply a plain text file installation key as file `matlab.fik`, the license file as `matlab.lic`, the software tarball as `matlab.tar`.
## To perform a network install set $_networkinstall to true.
