; RUNSTART.ASM[REL]

; This code is assembled as a relocatable library and linked at the beginning
; of the program using it. It works with the companion file RUNEND.ASM[REL],
; which has to be linked at the end of the binary.

; Together, these perform initialization tasks for the memory allocator code
; and then jump to the program's entry point, defined as the "main" global
; symbol.
