Replace "aimap" with the name of your preferred pretty printer program.
`aimap' itself is not a pretty printer, but a perl-script that changes
the case of keywords and identifiers (Ada Identifier case MAPping
tool).  It is written by Tom Quiggle from Silicon Graphics who posted it
here on comp.lang.ada.

Type `C-c C-t i' for the if-statement template.  `ada-stmt.el' is
intended for that purpose.  It does not extend the just typed
characters, but wants a special key sequence for every construct.  I
admit that it is not very practical, but I just copied it from the
original `ada.el'.  Statements based on abbreviations do not (yet)
exist.

As the name implies `ada-external-pretty-print-program' is the name of
an *external* program that you have to get from somewhere else.  I can
send you `aimap' if you want to (or Tom Quiggle posts it here again)

CM> to reconfigure my .emacs file?

Put that line in your `.emacs'

(setq ada-external-pretty-print-program "<name-of-my-pretty-printer>")

Most compilers come with a pretty printer. At least Alsys (now Tomson
Software Products) and VADS (Verdix, now Rational) provide such a program.

I hope that helps. Don't hesitate to ask again.

There is a file `ada-verdix.el' in the contrib directory of
emacs-ada-mode-2.12.
