Yeah, the NAnt script would use the <exec> task to call the program with the
argument specifying what environment it was building from. So in Ant terms:
<for list="dev,qa,uat,prod" param="environment">
<exec dir="." executable="configure.exe">
<arg line="@{environment}"/>
</exec>
<now configs are set correctly so you stage it for deploy and package it
for that environment using your favorite installation tool/>
</for>

Subject: Re: Merge base settings with environment specific ones
Thanks Eric. If I understood you correctly, it's that program you wrote that
did the trick for you, not the NAnt script. Is it correct? Thanks.
