To install, open a command line and type the following, repeating 2-4 until there are no warnings: 1. `lualatex mandi.ins` (can also use latex) 2. `lualatex mandi.dtx` (lualatex is required) 3. `makeindex -s gind.ist -o mandi.ind mandi.idx` 4. `makeindex -s gglo.ist -o mandi.gls mandi.glo` Move the `*.sty` files into a directory searched by TeX.
