How to write comments in maxima session inside texmacs



I tried


(%i3)  /* to plot a circle whose equation is x^2 + y^2 + 5*x + 5*y - 6 = 0 */


  Incorrect syntax: Premature termination of input at ;.

  *x + 5*y - 6 = 0 */;

Any other ideas?

using texmacs 1.0.5-2, 5.9.1-9 on Debian Sid machine.

thanks
