-    /// Documentaaaaaaaaaaaaation
+    /// Allows programs containing unsupported maps for the current kernel to be loaded
+    /// by skipping map creation and relocation before loading.
+    /// 
+    /// This is useful when you have a single program containing e.g. a `RingBuf`
+    /// and a `PerfEventArray` and you decide which one to use before loading the bytecode.
+    /// Can be used with `.set_global()` to signal if the map is supported.
+    /// 
+    /// # Example
+    /// 
+    /// ```no_run
+    /// use aya::EbpfLoader;
+    /// use aya_obj::btf::Btf::bpf_map_type;
+    /// 
+    /// let mut set = HashSet::new();

+    /// let ebpf = EbpfLoader::new()
