+ * This function takes the raw data block set up by the ELF loader

*
* The arguments are:
- * elfdata -- The ELF loader data block; usually from the stack.
- * Basically a pointer to argc.
- *
- * onexit -- Function to call on exit, can be NULL.
- *
- * slingshot -- Address of the program's main function

- * structors -- Table of constructor functions arrays that must
- * be called before the slingshot.
