New submission from Alexander Solovyov <pira...@piranha.org.ua>: Often it is useful to access some variable in other section for interpolation needs: for example, parent directory declared in common section could be used in configuration of certain components. Included patch can fix that (using syntax 'section.variable'), is there any chances that it could be applied? :)
