+# @ECLASS-VARIABLE: EGIT_CLONE_TYPE
+# @DESCRIPTION:
+# Type of clone that should be used against the remote repository.
+# This can be either of: 'mirror'.
+#
+# The 'mirror' type clones all remote branches and tags with complete
+# history and all notes. EGIT_COMMIT can specify any commit hash.
+# Upstream-removed branches and tags are purged from the local clone
+# while fetching. This mode is suitable for cloning the local copy
+# for development or hosting a local git mirror. However, clones
+# of repositories with large diverged branches may quickly grow large.
