New in 1.0pre4:
* --enable-opt became --enable-optimize in configure script
* Fixed boundary and surface mesh association for variationnal
  formulae.
* Plugged P1 FEM functions derivatives evaluation

New in 1.0pre3:
* Added examples/ to tarball distribution (at last)
* Improved documentation generation (pdf and ps)
* Improved mesh reader (no more crash with Ridges, Edges and Corners)
* convection operator is now implemented for Tetrahedral meshes.

New in 1.0pre2:
* ff3d is distcheck clean now (prudhomm@debian.org)
* closed Bugs (see http://savannah.nongnu.org/bugs/?group=ff3d)
  #6932: "Not enough precise evaluation of domain intersection"
  #6933: "File presence not tested"
  #7461: "add 'inverse' keyword"
  #7482: "Sparse matrix initialization"
  #7545: "Not implemented output for boolean functions"
  #8139: "parse.ff.yy failes to compile with -Ox x>=1"
  #8140: "default compilation flags are not good"
* fixed center of mass for reference tetrahedron: (0.5,0.5,0.5) was
  used.
