Subject RE: Improt task and project basedir

Since a property can be used in different contexts (like <fileset
dir="${dir}/.." includes="${dir}/"/>) and in general we might not want to
change the property string value, but we still need to rebase it. One of the
possibility is to use a "shadow" property with a different name. Another way
is to store multiple values in one property for different contexts. Rebased
value will be calculated lazily or during the property setting (the build
file's base dir is available here). After that ANT could provide different
property values depending on a context - string value, path value (and
possibly path list value). I still think it would be great to have <property
name="xxx" path="yyy;zzz"/> - it will make rebasing much simpler, since it
is now clear how to rebase the property.

Could you please explain more in detail about this solution? Thanks :-)
