The
template::util::write_file proc is basically just
using
puts to write your string to a file. So you need
to have actual linefeeds in the string you pass to it, not the literal
string "\n". Either make sure your "\n" is interpreted at the time
you set your string, or if necessary (unlikely), call subst on the
string later on, just before you pass it to
template::util::write_file.
Also, my advice is when you have a chance, review Tcl's rules for
parsing and evaluation, as this sort of problem indcates you haven't
become completely familiar with them yet.
