Subject: Using configuration files (replacing shellscripts)

Hi!

I want to use configuration files in order to save values, directories,
and files. I did some googeling to find out that the ruby community
often suggests ruby-files (hashes) to save configurations. These
rb-files are read in by interpreting. (btw, anyone suggests a cool
part of code for this with errorhandling and so on?)

But I do have some problems with that method:

,----[ shellscript configuration example ]
| export value1=42
| export value2=23
| export path1=/some/where
| export path2=$path1/else
| export file1=$path1/foo
| export file2=$path2/bar
`----

First, I tried to replace it 1:1 using ruby but failed when it came to
reusing values:

,----[ woun't run ]
| $config = {
|   'value1' => '42',
|   'value2' => '23',
|   'path1' => '/some/where',
|   'path2' => $config['path1']+'/else',
|   [...]
| }
`----

Is there a way to accomplish this in another way? (using self or
something like that)

Meanwhile I did a workaround:

,----[ Workaround ]
| $directories = {
|   'path1' => '/some/where',
|   'path2' => '/some/where/else',  # redundancy! :-(
|   [...]
| }
| 
| $files = {
|   'file1' = $directories['path1']+'/foo', # problem!
|   [...]
| }
| 
| $values = { ... }
`----

This did not work out either. How can I solve my problem?
