-// rsbegin.o and rsend.o are the so called "compiler runtime startup objects".
-// They contain code needed to correctly initialize the compiler runtime.
-//
-// When an executable or dylib image is linked, all user code and libraries are
-// "sandwiched" between these two object files, so code or data from rsbegin.o
-// become first in the respective sections of the image, whereas code and data
-// from rsend.o become the last ones. This effect can be used to place symbols
-// at the beginning or at the end of a section, as well as to insert any required
-// headers or footers.
-//
-// Note that the actual module entry point is located in the C runtime startup
-// object (usually called `crtX.o), which then invokes initialization callbacks
-// of other runtime components (registered via yet another special image section).
