 ## HRG Generation {#what-it-does}
 
 All [text conversion tools](@), including the [HRGT](@), convert (input) text files into results (output text files) by locating particular text patterns, doing some processing, and constructing texts that are used to replace the located text patterns with. This is illustrated in the figure below, and further explained in the page [TEv2 Text Conversion](/docs/overview/tev2-text-conversion):
