 * The program loader is a special init binary. Its image is used
- 
 
 38 
 * to create a new task upon a @c task_spawn syscall. The syscall
- 
 
 39 
 * returns the id of a phone connected to the newly created task.
- 
 
 40 
 *
- 
 
 41 
 * The caller uses this phone to send the pathname and various other
- 
 
 42 
 * information to the loader. This is normally done by the C library
- 
 
 43 
 * and completely hidden from applications.
