That's the problem, that I do not have clear how to do it.
Not so long ago I made a rule for compiling cuda-files. Here is a 
shortened version:

Module {
     id: cuda
     Depends { name: "cpp" }

     FileTagger {
         patterns: "*.cu"
         fileTags: ["cuda"]
     }

     Rule {
         id: cudaCompiler
         inputs: ["cuda"]
         auxiliaryInputs: ["hpp"]

         Artifact {
             fileTags: ["obj"]
             filePath: FileInfo.joinPaths(".obj", 
Utilities.getHash(input.baseDir), input.fileName + ".o")
         }

         prepare: {
             var args = [];
             args.push(...);

             var cmd = new Command("/usr/bin/nvcuda", args);
             cmd.description = 'cuda compiling ' + input.fileName;
             cmd.highlight = "compiler";
             return cmd;
         }
     }
}

Everything is clear: there are files with the extension 'cu', the files 
are connected to the project. And there is a cuda compiler: /usr/bin/nvcuda.

In the current project, instead of /usr/bin/nvcuda, the newly-built 
utility should be used (call it sonnet_parsetrigrams). I do not 
understand how to write it down. Also what should I write in the 
FileTagger section? Files do not have an extension, these files are not 
connected to the project. All that is - the name of the directory in 
which these files are located.  The call of the utility is as follows: 
sonnet_parsetrigrams MyProjectDir/trigramsDir > trigrams.map
