+- Not suitable for repositories with many branches, a quite linear history is

+- Relatively slow to run the first time (about 3 seconds for sbase,

+  - file tree per commit.
+  - history log of branches diverged from HEAD.
+  - stats (git shortlog -s).
+
+  this is by design, just use git locally.
