+ Emacs-libvterm (vterm) is fully-fledged terminal emulator inside GNU
+ Emacs based on libvterm, a C library. As a result of using compiled
+ code (instead of elisp), emacs-libvterm is fully capable, fast, and
+ it can seamlessly handle large outputs.
+
+ This package automatically compiles the needed module and provides
+ configurations for better integration with some shells.
