+.. |summary| replace::
+ Today, ocaml is obsolete in the debian packages : the most of the
+ librairies are still linked with Ocaml3 althought Ocaml4 is out since
+ almost a year. When we need to develop with Ocaml4, we have to recompile
+ all the dependencies, but this implies to install them for the whole
+ system. But we can use a local repository with some findlib configuration.
+
+Findlib is now a required tool for an Ocaml project compilation. Each
+application uses now findlib for searching the dependencies, and the linking
+phase.
+
+We first need to create a local configuration in wich we write where to find
+the packages :
+
+
+.. code-block:: bash
+
+ destdir="/home/chimrod/ocaml/packages/"
+ path="/home/chimrod/ocaml/packages/:/usr/local/lib/ocaml/4.00.1:/usr/lib/ocaml:/usr/lib/ocaml/METAS"
+
+:destdir: is the path where we want to install the newly compiled packages.
+:path: is the path list where to find the packages.
+
+Of course, you need to replace `/home/chimrod/` by your own installation path.
+It must be an absolute path.
+
+The path to this file can be saved with the shell environnement ; we just need
+to reference it in the `.bashrc` file :
+
+.. code-block:: bash
+
+ export OCAMLFIND_CONF=/home/chimrod/ocaml/ocamlfind.conf
+
+That's now : each new package will now be installed in your packages directory,
+and the compilation will also look for this path for the required
+dependencies : you do not have to install the packages as root anymore.
