Well, I don't think

        @IncludeTxt { @Sh{echo $TXTFILE} }

is going to do anything sensible.  Since @IncludeTxt has a @Filter
parameter, its right parameter gets piped through the filter
absolutely unchanged, i.e.

        @Sh{echo $TXTFILE}

(literally) gets piped into txt2lout.  A filtered parameter is
passed into the filter absolutely unchanged, it doesn't get
evaluated by Lout first (indeed, if it did, the result would
be a parse tree, not a piece of text).

Hope this helps.
