sed(1) is good for replacing one word with another one -- but the OP
was talking about implementing something more along the lines of what
#include does with the C pre-processor.  sed can certainly help to do
that, but it's not a complete solution.

There's in fact plenty of different ways to do this sort of thing.
Some more practical than others.  (I once, a long time ago, wrote a
website using server-side includes to implement a templating system,
using 'lynx -dump' to get apache to process the source files.)

Probably the official way to do this sort of thing is to use a macro
pre-processor.  cpp(1) has often been used, but it is pretty C
specific.  m4(1) is the general purpose solution but it's got a lot of
capabilities and is intimidating to the beginner:

    % cat foo
    This is the included text
    % cat bar
    Some stuff
    Some more stuff
    A last chunk of stuff
    % m4 < bar 
    Some stuff
    Some more stuff
    This is the included text
    A last chunk of stuff
