+
+```
+tempfile=$(mktemp) \

+
+You can then set `term = "wezterm"` in your `.wezterm.lua` config file.

+Doing this will inform some software of newer, more advanced features such
+as colored underlines, styled underlines (eg: undercurl).  If the system
+you are using has a relatively outdated ncurses installation, the `wezterm`
+terminfo will also enable italics and true color support.
