+readability-function-size
+=========================
+
+`google-readability-function-size` redirects here as an alias for this check.
+
+Checks for large functions based on various metrics.
+
+Options
+-------
+
+.. option:: LineThreshold
+
+   Flag functions exceeding this number of lines. The default is `-1` (ignore
+   the number of lines).
+
+.. option:: StatementThreshold
+
+   Flag functions exceeding this number of statements. This may differ
+   significantly from the number of lines for macro-heavy code. The default is
+   `800`.
+
+.. option:: BranchThreshold
+
+   Flag functions exceeding this number of control statements. The default is
+   `-1` (ignore the number of branches).
+
+.. option:: ParameterThreshold
+
+   Flag functions that exceed a specified number of parameters. The default
+   is `-1` (ignore the number of parameters).
+
+.. option:: NestingThreshold
+
+    Flag compound statements which create next nesting level after
+    `NestingThreshold`. This may differ significantly from the expected value
+    for macro-heavy code. The default is `-1` (ignore the nesting level).
