+# = Class: slurm::repo
+#
+# This class takes care of the control repository for the slurm configuration, which
+# version your slurm configuration files.
+# For many reasons, we decided NOT to directly version the /etc/slurm directory,
+# but rather to have a control repository cloned in another directory and
+# following a specific layout depicted below:
+#
+# * for the cluster '${clustername}', a root directory named'${clustername}'
+#   hosts all common slurm configuration files
+# * a script '${syncscript}' (typically 'bin/commit_slurm_configs.sh') is
+#   responsible for synchronizing the configuration and commit it into this
+#
+#   .

+#   |    └── commit_slurm_configs.sh
