NAME

       gnatpp - Ada pretty-printer

SYNOPSIS

       gnatpp [options] {filename | -files filename} [gcc_switches]

DESCRIPTION

       gnatpp recreates the source text of the specified Ada units from GNAT's parse tree.  Along
       the way, it reformats the source text according to the many  options.   The  defaults  are
       suitable for the GNAT style guide.
