+# opengl
+An OpenGL interface
+
+# Extension loading
+``loadExtensions()`` must be executed after the creation of a rendering context and before any OpenGL extension procs are used.
+
+# Automatic error checking
+The OpenGL procs do perform automatic error checking by default. This can be disabled at compile-time by defining the conditional symbol ``noAutoGLerrorCheck`` (-d:noAutoGLerrorCheck), in which case the error checking code will be omitted from the binary; or at run-time by executing this statement: ``enableAutoGLerrorCheck(false)``.
