+version-number is a floating point number giving the version of

 Gmsh Binary Post-Processing File Format
 =======================================
 
-    The binary post-processing file format is the same as the ascii file format,
-    except that:
-    - the format field is the following
-      $PostFormat
-      version-number 1
-      $EndPostFormat
-    - all double precision vectors ('time-step-values', 'SP-values', 'VP-values', etc.)
-      are written in binary format
-    - AND there is an additional integer written before the 'time-step-values', and
-      which contains the value '1'. This integer serves as a test for little/big endian
-      detection.
-
-    Here is an example, of C code to write a view in binary format (nb-SP, nb-VP, ...
-    have their classical meaning; SP-values, VP-values, ... are arrays of double
-    precision numbers containing respectively nb-SP, nb-VP, ... 'SP-value'. 
-    'Time-values' is an array of 'nb-time-step' double precision numbers):
-
-    int one=1;
-
-    fprintf(file, "$View /* test */\n");
-    fprintf(file, "test %d %d %d %d %d %d %d %d %d %d %d %d %d\n", 
-	    nb-time-step, 
-            nb-SP, nb-VP, nb-TP, nb-SL, nb-VL, nb-TL, 
-            nb-ST, nb-VT, nb-TT, nb-SS, nb-VS, nb-TS);
-    fwrite(&one, sizeof(int), 1, file);
-    fwrite(Time-values, sizeof(double), nb-SP, file);
-    fwrite(SP-values, sizeof(double), nb-SP, file);
-    fwrite(VP-values, sizeof(double), nb-VP, file);
-    fwrite(TP-values, sizeof(double), nb-TP, file);
-    fwrite(SL-values, sizeof(double), nb-SL, file);
-    fwrite(VL-values, sizeof(double), nb-VL, file);
-    fwrite(TL-values, sizeof(double), nb-TL, file);
-    fwrite(ST-values, sizeof(double), nb-ST, file);
-    fwrite(VT-values, sizeof(double), nb-VT, file);
-    fwrite(TT-values, sizeof(double), nb-TT, file);
-    fwrite(SS-values, sizeof(double), nb-SS, file);
-    fwrite(VS-values, sizeof(double), nb-VS, file);
-    fwrite(TS-values, sizeof(double), nb-TS, file);
-    fprintf(file, "$EndView\n");
+The binary post-processing file format is the same as the ascii file format,
+except that:
+
+1) file-type equals 1.
+
+2) all lists of double precision numbers are written in binary format
+
+3) there is an additional integer, of value 1, written before
+   time-step-values. This integer serves to detect if the computer on
+   which the binary file was written and the computer on which the
+   file is read are of the same type (little or big endian).
+
+Here is an pseudo C code to write the beginning of a post-processing
+file in binary format:
+
+int one = 1;
+
+fprintf(file, "$PostFormat\n");
+fprintf(file, "%g %d\n", 0.995, 1);
+fprintf(file, "$EndPostFormat\n");
+
+fprintf(file, "$View\n");
+fprintf(file, "%s %d %d %d %d %d %d %d %d %d %d %d %d %d\n", 
+        view-name, nb-time-steps,
+        nb-scalar-points, nb-vector-points, nb-tensor-points,
+        nb-scalar-lines, nb-vector-lines, nb-tensor-lines,
+        nb-scalar-triangles, nb-vector-triangles, nb-tensor-triangles,
+        nb-scalar-tetrahedra, nb-vector-tetrahedra, nb-tensor-tetrahedra);
+fwrite(&one, sizeof(int), 1, file);
+fwrite(time-step-values, sizeof(double), nb-time-steps, file);
+fwrite(all-scalar-point-values, sizeof(double), all-scalar-points, file);
+...
+fprintf(file, "$EndView\n");
+
+In this pseudo-code, all-scalar-point-values is the array of double
+precision numbers containing all the scalar-point-value lists, put one
+at the end of each other in order to form a long array of double. The
+principle is the same for all other kinds of values.
 
 
 Gmsh Parsed Post-Processing Format
 ==================================
 
-   For testing purposes (or with very small data sets), there is an additional,
-   post-processing format which is parsed by the same grammar analyser as the
-   geometry. You can thus for example embed small post-processing views into your
-   geometrical descriptions.

-Gmsh . Eventually, the most difficult thing about Gmsh is to find a way to
-pronouce 'Gmsh'...
+Gmsh is an automatic three-dimensional mesh generator, primarily Delaunay,
+with pre- and post-processing facilities. Its primal goal is to provide a
+simple meshing tool for academic test cases with parametric input and up to
+date visualization capabilities.  One of the strengths of Gmsh is its
+ability to respect a characteristic length field for the generation of
+adapted meshes on lines, surfaces and volumes. Gmsh requires OpenGL
+libraries to be installed in on your system.

+@cindex Reading, guidelines
+
+After reading @ref{General overview}, and @ref{Expressions}, which depict
+the general concepts and the way to construct simple expressions in GetDP,
+you can safely (in a first reading) skip @ref{Objects} and @ref{Types for
+objects} and directly go to @ref{Short examples}. This chapter gives simple
+examples of the problem definition syntax used to define the discrete
+problems. For each example, you should then go back to @ref{Objects}, and
+@ref{Types for objects}, and have a detailed view of the syntax of the
+objects appearing in it. Note that indexes for many concepts and for all the
+syntax elements are available at the end of this manual.
 
-@node Mesh, Post-Processing, Geometry, Top
-@unnumbered Mesh
+Once the examples presented in @ref{Short examples}, are understood, you
+may start to use GetDP on your computer (@pxref{Running GetDP}), for
+example by solving the complete examples presented in @ref{Complete
+examples}. Ready-to-use input files for these examples can be downloaded
+from the web site.

+@email{Remacle@@scorec.rpi.edu}.  Please send as precise a description of
+the problem as you can, including sample input files that produce the

+Install the 'info' version of this user's guide! On your (Unix) system, this
+can be done by 1) copying all getdp.info* files to the place where your info
+files live (usually /usr/info), and 2) issuing the command 'install-info
+/usr/info/getdp.info /usr/info/dir'. You will then be able to access the
+documentation with the command 'info getdp'. Note that particular sections
+("nodes") can be accessed directly. For example, 'info getdp functionspace'
+will take you directly to the definition of the FunctionSpace object.
+@item
+Use emacs to edit your files, and load the C++ mode! This permits automatic
+syntax highlighting and easy indentation. Automatic loading of the C++ mode
+for @file{.pro} files can be done by adding the following command in your
+@code{.emacs} file: @code{(setq auto-mode-alist (append '(("\\.pro$"
+. c++-mode)) auto-mode-alist))}.
