this is /bin/sh syntax, not tcl; c.f. man sh :

       $@      Expands to the positional parameters, starting from
               one.  When the expansion occurs within double-
               quotes, each positional parameter expands as a sep-
               arate argument.  If there are no positional parame-
               ters, the expansion of @ generates zero arguments,
               even when @ is double-quoted.  What this basically
               means, for example, is if $1 is ``abc'' and $2 is
               ``def ghi'', then "$@" expands to the two argu-
               ments:
               "abc"   "def ghi"


Cheers,

Daniel
