                            The install Command

   Usage

   install [-interactive] [-debug] [-cc <c_compiler>]
   [-skip_c_compilation]

   The install command is the installation program for SmartEiffel The
   GNU Eiffel Compiler.
   This command (class install.e) is written entirely in Eiffel and is
   the one recommended for installing SmartEiffel The GNU Eiffel
   Compiler.

   The install.e source code as well as the generated C code install.c
   are in the SmartEiffel directory.

   The very first step in installing SmartEiffel is to unpack the
   SmartEiffel directory somewhere on disk. The second step is to set the
   "SmartEiffel" environment variable to the full path leading to the
   "SmartEiffel/sys/system.se" file. The last step is to compile the
   install.c (it is precompiled for Windows) file and to run it from the
   SmartEiffel directory.

   The install command will do the rest of the work and will try to
   report possible problems. See the examples below.

   Example for UNIX

   As an example, we assume below that we want to install SmartEiffel in
   the directory /foo/SmartEiffel/. If you are using bash, add the
   following two lines to your .bashrc file:

     export SmartEiffel=/foo/SmartEiffel/sys/system.se
     export PATH=/foo/SmartEiffel/bin:$PATH

   If you are using csh or tcsh, add the following two lines to your
   .cshrc file:

     setenv SmartEiffel /foo/SmartEiffel/sys/system.se
     setenv PATH /foo/SmartEiffel/bin:$PATH

   Don't forget to open a new terminal window in order to take into
   account the new settings of the SmartEiffel and PATH variables. Then,
   in this new terminal window, just type the following commands:

     cd /foo
     gunzip se.tgz (or bunzip2 se.tar.bz2)
     tar xvf se.tar
     cd SmartEiffel
     make

   You now just have to wait for the compiler installation to complete.
   Actually, it may take some time because all of the tools are
   recompiled from scratch using the Eiffel source code of SmartEiffel
   itself.

   If you want to select manually the C compiler to be used (the default
   under UNIX is gcc), you should consider typing "make interactive"
   instead of just "make" (see the description of the -interactive option
   below). If your system has no gcc installed, compile install.c
   yourself and run it with -interactive option.

   Example for Windows

   The first step under Windows is to get a C compiler working on your
   computer. If you don't already have a C compiler installed, I
   recommend the LCC-Win32 compiler (a free C compiler system for Windows
   by Jacob Navia, http://www.cs.virginia.edu/~lcc-win32/ or
   http://www.q-software-solutions.com/lccwin32/).

   At this point, it is assumed you have a C compiler installed. Further,
   we assume below that we want to install SmartEiffel in the
   C:\SmartEiffel directory. The most difficult step now is to set the
   "SmartEiffel" variable to the appropriate value, which is actually:
   "C:\SmartEiffel\sys\system.se". Setting environment variables is
   different from one Windows system to another. For example, on Windows
   NT you have to look in the system windows to change environment
   variables. On Windows 95, you have to add the following two lines to
   your AUTOEXEC.BAT file:

     set SmartEiffel=C:\SmartEiffel\sys\system.se
     set PATH=C:\SmartEiffel\bin:%PATH%

   The last step is to open a DOS command window and to type the
   following commands:

     C:
     cd SmartEiffel
     install.exe

   You now just have to wait for the compiler installation to complete.
   Actually, it may take some time because all of the tools are
   recompiled from scratch using the Eiffel source code of SmartEiffel
   itself.

   Example for Other Systems

   For elate and OpenVMS systems, you can use "make elate" or
   "make openvms".
   On other systems, the very first step for installation is to compile
   the install.c file in order to run it.

   Options

   -interactive:
          By default, the install command tries to determine
          automatically the system name as well as the C compiler name.
          When the -interactive flag is used, the user is interactively
          prompted for the system name and the C compiler to use as well
          as some other crucial information. When all of the information
          has been interactively gathered, the command prompts for
          confirmation before starting the remainder of the installation
          process automatically. Using the -interactive flag first is a
          good idea, to see the list of supported systems and C
          compilers.
   -debug:
          Displays a lot of information useful for debugging the
          installation process. It is also interesting if you are curious
          to see what the install command is really doing (or trying to
          do ;) ).
   -cc <c_compiler>:
          By default, install interactively asks for the C compiler to
          use. With this option specified, it skips this query and uses
          c_compiler. This c_compiler name must be one of the supported C
          compilers (e.g. gcc). This is mostly useful for system-specific
          installation scripts that execute install as part of it.
   -skip_c_compilation:
          Assumes that all commands are already compiled and their
          executables exist. This is useful only for binary
          distributions.
