I need some help from sh/bash experts: How can I print the paths and
have all the variables expanded/substituted? Example:
  echo "Configuration files: " ${sysconfdir}
results in:
  Configuration files:  ${prefix}/etc
I would like to see "/usr/local/etc".

To work-around that, I can use eval, like that:
  echo "Configuration files: " `eval echo ${sysconfdir}`
  
Works for $sysconfdir but not for e.g. libdir, because there is one
more level of sustitution.

Any ideas?

Bye,
