How to call script SMD Import of Source_Tools from Command Line ?

https://developer.valvesoftware.com/wiki/Blender_Source_Tools
I using Blender 2.68
I loaded this add-on

I think I start with
import io_scene_valvesource
But I don’t know how to call script

the easiest way is probably to call the operator: bpy.ops.import_scene.smd()

parameters are:

<b>filepath </b>= StringProperty(name="File Path", description="File filepath used for importing the SMD/VTA/DMX/QC file", maxlen=1024, default="")
<b>append </b>= BoolProperty
<b>doAnim </b>= BoolProperty
<b>upAxis </b>= EnumProperty(default='Z')
<b>makeCamera </b>= BoolProperty
<b>rotModes </b>= ( ('XYZ', "Euler", ''), ('QUATERNION', "Quaternion", "") )
<b>rotMode </b>= EnumProperty(default='XYZ')
<b>boneMode </b>= EnumProperty(items=(('NONE','Default',''),('ARROWS','Arrows',''),('SPHERE','Sphere','')))
