    33== Overview == 
    4 The WHIZARD / O'Mega interface generates the model files necessary for the inclusion of a FeynRules model into the WHIZARD / O'Mega framework. All versions of WHIZARD / O'Mega >= 1.92 are supported. 
     4The WHIZARD / O'Mega interface generates the model files necessary for the inclusion of a FeynRules model into the WHIZARD / O'Mega framework. All versions of WHIZARD / O'Mega >= 1.92 are supported. A more verbose reference to the interface can be found in  [http://arxiv.org/abs/1010.3251 arXiv:1010.3251] .

    66== Usage: all versions == 
     
    11112. {{{WriteWOOutput[{LagrangianList}, Options]}}} 
    1212 
    13 3. {{{WriteWOOutput[Null, WOVertexList->{VertexList}, Options]}}} 
     133. {{{WriteWOOutput[Input->{VertexList}, Options]}}}

    1515Version 1. operates on a single Lagrangian, while 2. operates on a list of Lagrangians and 3. takes a list of FeynmanRules as an argument. The following options are available: 
    1616 
    17  * {{{WOVertexList}}}: If {{{=!= Null}}}, this is interpreted as a list of Feynman rules and overrides any Lagrangian (or -list) specified (in this case, {{{Null}}} is accepted as first argument). Default: Null 
     17 * {{{Input}}}: Directly specify a vertex list instead of having the interface call {{{FeynmanRules}}} in order to extract the vertices from a Lagrangian. The Lagrangian is ignored and can be omitted if this option is used. Note that the list must be flavor expanded. 
    1818 * {{{WOModelName}}}: The name by which the model will be identified in WO. Note that all models for W1.9x have to start with "fr" (e.g. {{{WOModelName->"fr_sm"}}}) if they are to be picked up by WO1.9x without user intervention (no such restriction exists for W2). Beware that the interface may modify this name if it doesn't fit into the WO naming schemes --- double check the generated messages to be sure. Default: derived from the FR model name 
    1919 * {{{WOMaxNcf}}}: Upper limit on the number of color flows which the generated code will be able to handle (essentially n_8 - n_3 / 2, where n_8 is the maximum number of external octets and n_3 that of external triplets). Irrelevant for W2; also, the technically inclined user can change this after running the interface in {{{f90_modellname_Col.ml}}}. Default: 4 
     
    2424 * {{{WOGaugeParameter}}}: The parameter which takes the role of \xi in the Rxi gauges, can be either a string or a symbol. Note that this parameter is automatically added to the parameter list if WOAutoGauge is set to {{{True}}}. Default: "Rxi" 
    2525 * {{{WOWhizardVersion}}}: Select the WO version for which you want to generate code. Possible choices: 
    26   * {{{"1.92"}}}: WO 1.92 
    27   * {{{"1.93"}}}: WO 1.93 - 1.95 
    28   * {{{"2.0" }}}: WO 2.0 (default) 
     26  * {{{"1.92"}}}:  WO 1.92 
     27  * {{{"1.93"}}}:  WO 1.93 - 1.95 
     28  * {{{"1.96"}}}:  WO 1.96 
     29  * {{{"2.0" }}}:  WO 2.0 
     30  * {{{"2.0.3"}}}: WO 2.0.3 (default) 
    2931 * {{{WOVerbose}}}: Verbose output. At the moment, this gives detailed information on skipped vertices. Default: False 
    3032 * {{{WOAutoGauge}}}: Automagically assign goldstone boson masses and add the gauge parameter to the parameter list (in the case of Rxi gauge). Default: True 
     
    3436 * {{{Output}}}: The output directory which will contain the generated model files. Default: derived from the FR model name 
    3537 
    36 It is wise to '''check the messages the interface generates''' while it runs; i these will inform you about any unidentified vertices that have been skipped as well as of most other noteworthy caveats concerning the generated code.
