+Shell completion |
+-----------------+
+
+crosstool-NG comes with a shell script fragment that defines bash-compatible
+completion. That shell fragment is currently not installed automatically, but
+this is planned.
+
+To install the shell script fragment, you have two options:
+ - install system-wide, most probably by copying ct-ng.comp into
+   /etc/bash_completion.d/
+ - install for a single user, by copying ct-ng.comp into ${HOME}/ and
+   sourcing this file from your ${HOME}/.bashrc
