I can't find a description of the use of the percent glyph (%) in either the NAMD or Tcl documentation (except as an infix operator for arguments to expr).

The Martini RBCG tutorial's example .conf file ends with:

run 1000000
%set totsimtime 5000000
%run [expr $totsimtime - $currenttimestep]

What are those '%'s for?
