# OBSOLETE # Syntax:

# OBSOLETE # /bin/sh mainloop.in command

# OBSOLETE #

# OBSOLETE # Command is one of:

# OBSOLETE #

# OBSOLETE # init

# OBSOLETE # support

# OBSOLETE # extract-{simple,scache,pbb}

# OBSOLETE # {full,fast}-exec-{simple,scache,pbb}

# OBSOLETE #

# OBSOLETE # A target need only provide a "full" version of one of simple,scache,pbb.

# OBSOLETE # If the target wants it can also provide a fast version of same.

# OBSOLETE # It can't provide more than this, however for illustration's sake the FR30

# OBSOLETE # port provides examples of all.

# OBSOLETE

# OBSOLETE # ??? After a few more ports are done, revisit.

# OBSOLETE # Will eventually need to machine generate a lot of this.
