Readline Init File

Although the Readline library comes with a set of Emacs-like
keybindings installed by default, it is possible to use a different set
of keybindings.  Any user can customize programs that use Readline by
putting commands in an "inputrc" file, conventionally in his home
directory.  The name of this file is taken from the value of the
environment variable `INPUTRC'.  If that variable is unset, the default
is `~/.inputrc'.
   When a program which uses the Readline library starts up, the init
file is read, and the key bindings are set.
   In addition, the `C-x C-r' command re-reads this init file, thus
incorporating any changes that you might have made to it.
