Nico,
I had this same problem at one point in time, but was able to change it to the
${...} syntax which works beautifully. I know that you cannot use this syntax,
but I will tell you that I did find a work-around for the nested @...@ syntax.
The workaround is to run configure_file on the file twice. The nested @...@
symbols will always be replaced from the inside out which is the behavior that
you want, you just have to run configure_file on the file for as many nests
that you have. If the deepest nest you have is two nests, then you only need to
run configure_file twice. I know this is kind of a kludge to fix it, but it
does work from my experience...
Hope this helps...
Eric
