-\subsection{Environment variables}
-Two environment variables {\bf SOPHYABASEREP} and {\bf SOPHYACXX} are used 
+\subsection{Directories, environment variables, configuration files}
+The environment variable {\bf SOPHYABASE}  is used 
 to define the path where the Sophya libraries and executable are installed.
-{\bf SOPHYABASEREP} defines the base directory path and {\bf SOPHYACXX} the 
-name of the C++ compiler. The complete path is built using {\bf SOPHYABASEREP},
-the operating system name (as obtained by the {\tt uname} command), and
-the compiler name. In the example below, we show the complete path 
-for a {\tt Linux} system, using the GNU g++ compiler:
-
 \begin{itemize}
-\item \$SOPHYABASEREP/Include : Include (.h) files
-\item \$SOPHYABASEREP/Linux-g++/Libs : Path for the archive libraries (.a)
-\item \$SOPHYABASEREP/Linux-g++/ShLibs : Shared library path (.so)
-\item \$SOPHYABASEREP/Linux-g++/Exec : Executable file path
+\item \$SOPHYABASE/include : Include (.h) files
+\item \$SOPHYABASE/lib : Path for the archive libraries (.a)
+\item \$SOPHYABASE/slb: Shared library path (.so)
+\item \$SOPHYABASE/exe : Executable file path
 \end{itemize}
 
 In order to use the shared libraries, the {\bf LD\_LIBRARY\_PATH} variable
 should contain the Sophya shared library path 
-({\tt \$SOPHYABASEREP/Linux-g++/ShLibs } when using g++ compiler on Linux)
-
-For modules using external libraries, the {\bf EXTLIBDIR} 
-environment variable should contain the path to these libraries
-and corresponding include files.
-C-FitsIO anf FFTW include files should be accessible through: \\
-{\tt \$EXTLIBDIR/Include/FitsIO } \\
-{\tt \$EXTLIBDIR/Include/FFTW } \\
-The corresponding libraries are expected to be found in: \\
-{\tt \$EXTLIBDIR/Linux-g++/Libs} \\
-
-\subsection{User makefiles}
-The file {\tt \$SOPHYABASEREP/Include/MakefileUser.h} defines the compilation 
-flags and the list of Sophya libraries. It should be included in the 
-user's makefile. The default compilation rules assumes that the object (.o) 
-and executable files would be put in the following directories: \\
-{\tt \$HOME/`uname`-\$SOPHYACXX/Objs} \\ 
-{\tt \$HOME/`uname`-\$SOPHYACXX/Exec}.
-In the case of a {\tt Linux} system and using {\tt g++} as the C++ compiler, 
-these two directories would be translated to \\
-{\tt \$HOME/Linux-g++/Objs} and {\tt \$HOME/Linux-g++/Exec}. 
-The GNU make program should be used.
-\par
-The file {\tt Examples/auto\_makefile} defines the rules to compile
-a given source program, and link it against the Sophya libraries to produce
-an executable. The example below shows the steps to compile a program named
-{\tt trivial.cc }.
-\begin{verbatim}
-csh> cp Examples/auto_makefile makefile
-csh> cp Examples/ex1.cc trivial.cc
-csh> make trivial
-\end{verbatim}
-This command should compile the {\tt trivial.cc} file, 
-and link it against the sophya libraries. 
-The file {\tt Examples/ex\_makefile} provides another 
-example makefile.
+({\tt \$SOPHYABASE/slb }). \\
+On Silocon Graphics machines (IRIX64) , the default SOPHYA configuration
+correspond to the 64 bit architecture. 
+The environment variable { \bf LD\_LIBRARY64\_PATH } defines
+the shared library path in this case and should contain ({\tt \$SOPHYABASE/slb }.
+
+The configure script creates links for external libraries include files in : 
+\begin{itemize}
+\item \$SOPHYABASE/include/FitsIO : c-fitsio library include files
+\item \$SOPHYABASE/include/FFTW : FFTW library include files
+\item \$SOPHYABASE/include/XAstro : XEphem library include files
+\end{itemize}
+
+The directory { \tt \$SOPHYABASE/include/SophyaConfInfo/ } contains files
+describing the installed configuration of SOPHYA software.
+
+The file { \tt \$SOPHYABASE/include/machdefs.h } contains definitions
+(flags, typedef) used in SOPHYA. 
+
+The file { \tt \$SOPHYABASE/include/sophyamake.inc } contains the 
+compilation commands and flags used for building the software. 
+Users can use most of compilation and link commands defined in this file:
+ {\tt \$CCOMPILE , \$CXXCOMPILE . \$CXXLINK \ldots}. 
+ (See module Example).
+
+The configure script (BuildMgr/configure) creates the directory tree and the
+above files.
