replacement of variable placeholders in files

[Dizzy]

Hi

I have an input file named project.conf.in in which I have some variable 
placeholders of the form ${VARIABLE}. I am trying to use sed to replace them 
with some actual contents so I have added a make rule in Makefile.am such as:

project.conf:project.conf.in $(top_builddir)/config.status
$(SED) -e 'address@hidden/@'"${localstatedir}/@g" 
$(top_srcdir)/conf/project.conf.in > $@

Notice that I first have a string with single quotes so I tell bash to not 
deal with ${LOCALSTATEDIR} then I have a string with double quotes so bash 
can replace the ${localstatedir} variable contents and no space between which 
seems to work well if I run that command in shell.

However I think that configure replaces the ${LOCALSTATEDIR} from the 
generated Makefile.in with "" (because there is no such variable so it puts 
an empty string) and ignores my single quotes.

Any idea how to implement such a make rule that should replace variable 
placeholders with contents of actual variables?

Thanks!
