#' \code{getopt_specification_matrix} returns a getopt specification matrix.
#'
#' @param specification_file a cvs file within the \code{galaxy_tool_directory} which stores getopt specification matrix data.
#' The first column are short flags, the second column are argument masks, the third column
#' is data types. The fourth column are variable names used in the tool XML. These three columns are required.
#' @param gtg_name the name of a running GTG.
