+- a `bin` directory containing custom scripts
+- bash configuration files

+
+```sh
+graffy@graffy-ws2:~/work$ git clone git@vmgit.ipr.univ-rennes.fr:graffy/graffyworkenv.git graffyworkenv.git

+
+then install the environment by creating symbolic links in your home dir that point to some files in the `local_repos_path`
+```sh
