In many systems, there's a framework program that reads a lot of
control files which describe the bits of work to be done.  The
framework program figures out the sequencing and dependencies of the
various bits of work, while there are separate programs that *execute*
the bits of work.  And the names of the execution programs are not
hard-coded within the framework program, they are specified in the
control files.  That sort of structure makes the framework program
simpler, and enforces a defined interface between the framework
program and the execution programs.  It also makes it easy to add new
execution programs without changing the framework program.
