+RULES FOR CORRECT USE OF THIS PACKAGE
+
+CVS Maintainer: Herve Bronnimann (hbronni@sophia.inria.fr)
+CVS Write-access: herve, geert-jan, sylvain, stefan
+
+IMPORTANT FILES:
+* changes.txt: records a succinct description of the changes between
+  releases. Put the latest (non submitted) changes at the top under no
+  release numbers.
+  Please, anytime you add something, modify this file (with your
+  name between brackets, see Sylvain's entries).
+* include/CGAL/* : the source files. There is no web/ subdirectory.
+  Please therefore comment the source code appropriately.
+* Makefile : has some nice targets for releasing the packages. You must
+  use gmake.
+* version: can be changed easily by "make VERSION=3.X.Y version"
+
+COMMON COMMANDS:
+
+cvs update : before starting your work (make sure you have the latest)
+
+{vim,emacs,ed,...} include/CGAL/Cartesian/* : modify the sources
+
+make test : try to see if you still work. Try not to modify the
+  local test-suite. The test makefile has been patched to include also
+  the other Cartesian packages. For this to work, you must have
+  Cartesian_basic, C2 and C3 in the same directory.
+
+cvs commit : commit your changes. Always cvs update before just to make
+  sure you'll have no conflict. As for the log file, I usually enter the
+  line(s) that I added in changes.txt (it's a good check if you did
+  modify that file...)
+
+MAKING A RELEASE OF THE PACKAGE: (please ask herve first, or if he's away)
+
+Try "make package" first. Then "make test". If it works, you might have
+a good package. Note: sometimes, the change will only be good if you
+submit both C2 *and* Cartesian_basic. Otherwise, you might break the
+release.
+
+Then please patch the makefile for your own target (like "make
+submit-geert"). Currently "make submit" will only work on the INRIA
+machines.
+
+NOTES:
+Please add your comments below, if you think something is wrong or misstated.
