-Do not forget to:
-* update file "options.cpp":
-  - add following include line
-        #include "${h_file}"

-        NOL_INSERT("${name}", "description...",

-* add new files in SCM repository, for example with:
+
+Check for differences, update algorithm description in "options.cpp",
+write your code in "${cpp_file}", and do not forget to add new files
+in SCM repository, for example with:
         \$ git add options.cpp ${h_file} ${cpp_file}
         \$ git commit -m 'Add algorithm ${name}."
