+Switching configuration after bootstrapping
+-------------------------------------------
+Let's assume that you want to switch what configuration autoproj is tracking,
+but without having to redo a complete bootstrap -- i.e. avoiding to rebuild
+stuff that is common between the configurations.
+
+autoproj provides the switch-config command for that. This command takes the
+same arguments than the bootstrap script, that is:
+
+autoproj switch-config \[vcs_type] \[vcs_url] \[vcs_options]
+{: .cmdline}
+
+As a shortcut, one can omit vcs_type and vcs_url if they don't change.
+This is especially useful when switching between branches:
+
+autoproj switch-config branch=experimental
+{: .cmdline}
