[Chimera-users] the version of Ambertools that are used in the command "Write prmtop"?

Dear Chimera's users, I built amber's .inpcrd and prmtop files using command write prmtop from Tools/Amber/Write Prmtop. I used Chimera 1.15 (build 42334), but how could I figure out what version of AmberTools is incorporated in this Chimera release? Best regards, Victor
