Variable substitution in source files

I have a number of files that need variable substitution, so I do this in 

        @rm -f foo
        @sed \
                -e 's,@@perlmoduledir@@,$(libexecdir)/perl,' \
                -e 's,@@swishbindir@@,$(bindir),' \
                -e 's,@@perlbinary@@,$(PERL),' \
                        $(srcdir)/ > foo

But I'm doing that in more and more files in my project 
tree -- and sometimes I need to do it to a file where there isn't a 
Makefile in that directory.

I'm feeling like I'm using the same bit of sed code in too many places.
Is there a better way to manage this?  I'd like to have the sed code 
(above) defined in one place and then maybe list all the files that need 
to be operated on.
