Include files are makefiles; they have to contain make syntax. As such,
they can take advantage of make techniques to customize their effective
content: use of variables, ifdef, eval, ...

A makefile can generate the files that it includes. A common example of
this is dependencies, like the -include .depend that appears in the 
chess
program's Makefile that you linked to earlier.

A makefile can generate an include file not only by executing a rule.
When make syntax is scanned, it's possible to execute external commands
via $(shell ...). Therefore this should be possible:

   DUMMY_VAR := $(shell command generating > foo.mk)

   # ... later

   include foo.mk

I.e. the updated foo.mk can be immediately available in the same make
invocation.
