This is all fully yet concisely documented in section 6.3 of The Exim
Specification, "6.3 File inclusions in the configuration file", which
states how early in the parsing process the inclusions are done, what
parsing steps happen _before_ the include processing, etc.
The Exim Specification is available online (via
www.exim.org and its
mirrors) and should also have been included with your distribution as a
plaintext file named "spec.txt".
Sections 6.3 through 6.9 are all likely to be of interest to you.
