Rename mopa.out to mopcopy, since it handles more than a.out these days.

|

/* mopcopy - Convert a Unix format kernel into something that
|
||||
* can be transfered via MOP.
|
||||
*
|
||||
* This code was written while refering to the NetBSD/vax boot
|
||||
* loader. Therefore anything that can be booted by the Vax
|
||||
* should be convertable with this program.
|
||||
*
|
||||
* If necessary, the a.out header is stripped, and the program
|
||||
* segments are padded out. The BSS segment is zero filled.
|
||||
* A header is prepended that looks like an IHD header. In
|
||||
* particular the Unix mahine ID is placed where mopd expects
|
||||
* the image type to be (offset is IHD_W_ALIAS). If the machine
|
||||
* ID could be mistaken for a DEC image type, then the conversion
|
||||
* is aborted. The original a.out header is copied into the front
|
||||
* of the header so that once we have detected the Unix machine
|
||||
* ID we can haul the load address and the xfer address out.
