Title written to the binary file:

     *   PARAMETER  VERSION 10 -- EXTENDED AND EXPLICIT SET -- 27 ATOM TYPES
     *   COMPILED BY WFVG, SNS AND BDO -- MARCH 1979
     *   HYDROGEN BOND PARAMETERS CHANGED FROM VERSION 5 -- ONLY O-O,O-N,N-N
     *   NONBONDED PARAMETERS FOR HYDROGEN (A-0.044,N-1,R-0.8 == EMIN-0.1)
     *   PHIS INVOLVING C(CARBONYL) AND NITROGENS MADE CONSISTENT IN VER. 8
     *   O-H BOND FORCE CONSTANTS CHANGED TO 400.0 IN VERSION 9
     *   ADDED ANGLE FOR N-TERMINAL PROLINE -- BRUC
     *   LAST UPDATE 16-Mar-1981  21:54:36

Additional angle for proline cropped up when a bug was found in PATEXH and explicit hydrogen topology file. The angle added was CH1E-NH3-CH2E which was given the parameters for HC-NH3-CH1E which appeared to be the closest angle to it. –Bruc
