Autodist prepares source tree for configuration, compilation and
distribution.  Prepares the source tree from the \`autodist.ad'
configuration file.  Generates Automake.am files from Automake.ad
files, configure.ac file from configure.ad file(s), generates the
configure script by running Autoconf tool, and generates Makefile.in
files by running Automake tool.
