how to put what i exuc in log

[Chenyang Feng]

our hamake file are like following:

<fold name="create_model_file">
    <input>
      <include idref="models"/>
      <include idref="serializer"/>
    </input>
    <output>
      <include idref="serialized_models"/>
    </output>
    <exec binary="/bin/bash ${bash_path}/create_serialized_model_file.sh">
      <parameter><literal value="-i ${models_table_name}"/></parameter>
      <parameter><literal value="-o ${serialized_models_filepath}"/></parameter>
      <parameter><literal value="-s ${serializer_filepath}"/></parameter>
    </exec>
  </fold>

I really want to see what command is this in the log file, like print out the sh file, print out the parameter, some thing i can use to check the bug

thanks
