In this included file, we also have some variables to be expansed, as <\$HOME> (bound in the Unix environment) or the INRIA's Rocquencourt campus adress (bound in the Htmlc expansion environment). We write:
\$inria_address
and since the variable (\$(inria_address)) is defined in the environment file ``$(environment_file_name)'', we obtain:
$inria_address
