    To install GNAT is a non-standard location you need to specify a
    base directory.  All the files will be installed in subdirectories
    that are created under this directory.

    Specify the base directory you want to use for installation:

EOF
  read basedir
  while true; do
    if [ X = X`echo $basedir|sed -n -e 's%^/.*%/%p'` ]; then\
      basedir=`pwd`/$basedir;\
    fi;\
    echo "    The base directory is $basedir";\
    echo "    To accept this choice enter RETURN.";\
    echo "    Otherwise type a new name.";\
    read answer;\
    if [ X$answer = X ]; then break; fi;\
    basedir=$answer;\
  done
  clear
  prefix=$basedir
  bindir=$prefix/bin
  libsubdir=$prefix/lib/gcc-lib/$machine/$basever
  cat << EOF

    The installation of GNAT will install:
      In $bindir :
          gcc gnatbind gnatbl

      In $libsubdir :
          gnat1 cc1 cpp ld libgcc.a specs
          libgnat.a, and libgthreads.a

      In $prefix/adainclude :
          The source files of the RTL

      In $libsubdir/adalib :
          The object files of the RTL

EOF
  echo make ins-all prefix=$prefix >$tmpout

  cat << EOF >env-vals
export GCC_EXEC_PREFIX=$libsubdir/
export ADA_INCLUDE_PATH=$prefix/adainclude
export ADA_OBJECTS_PATH=$libsubdir/adalib
export C_INCLUDE_PATH=$libsubdir/include
EOF

  cat << EOF
    The file env-vals has been created.  It contains the csh commands
    to set the environment variables you need to use GNAT.  These
    commands (or their equivalent for the shell you use) should be
    placed in your .cshrc (or equivalent) file.

  This script is provided to simplify the installation of the $machine
  binary version of the GNU NYU Ada Translator (GNAT).

  This script asks a few questions about how you want GNAT configured
  and then creates a file in this directory which can then be invoked
  to do the actual installation.  Running this configuration script will
  not modify anything anywhere else in your system.  You can break
  out of it or run it multiple times before doing the actual installation.

  Hit RETURN to continue.

  There are basically 3 options for installation:

  1) Install GNAT-specific files on top of an existing GCC $basever
     installation (must be in standard locations -- will likely
     require root permission).

  2) Install GCC C compiler and GNAT files in the standard  GCC locations.
     (Note: This includes directories under /usr.  On most
      systems, this requires root permission).

  3) Install GCC C compiler and GNAT files in non-standard locations
     that you will specify.


  Options 1 and 2 provide simplest and most flexible use of GNAT.
  Option 3 requires users to set some environment variables.
