+    __name__: should start with track_, time_ or mem_ to be collected by ASV
+    params and param_name: parameter matrix to display multiple graphs on the
+    same page.
+    pretty_name: If defined it's displayed in web-ui instead of __name__
+    (useful for revsets)
+    the module name is prepended to the benchmark name and displayed as
+    "category" in webui.
+
+    Benchmarks are automatically parameterized with repositories found in the
+    REPOS_DIR environment variable.
+
+    `params` is the param matrix in the form of a list of tuple
+    (param_name, [value0, value1])
+
+    For example [(x, [a, b]), (y, [c, d])] declare benchmarks for
+    (a, c), (a, d), (b, c) and (b, d).
