 #
-# * Make commands: all pb rd rd-force pb-force clean clean-all clean-pb clean-rd.
+# * Make commands: all pb rd rd-force pb-force clean clean-all.
 #
 # * pb: checks if dependencies exist and builds the Propel Builder project.
 #   (block design)
 # * rd: checks for dependencies and builds the Radiant Project
 #   based on Propel Builder Project.
+# * force: you can build the whole project without
+#   checking for dependencies.
 # * pb-force and rd-force: you can build the respective projects without
 #   checking for dependencies.
 # * clean: deletes the whole project and log files.
 # * clean-all: deletes all the generated files during build.
-# * clean-pb: deletes the Propel Builder project files and directories.
-#   After this you can rebuild the Propel Builder project separately by
-#   'make pb' but only if you created the project without using the '-sbc'
-#   template file option wich is used in official project creation command,
-#   because if you create with '-sbc' option the command will not create
-#   the project becouse the first <project_name> folder from
-#   <adi_project_folder>/<project_name>/<project_name> is not deleted,
-#   becouse that contains the Radiant project files. Also deletes the log
-#   file for Propel Builder project.
-# * clean-rd: cleans the content of <adi_project_folder>/<project_name>/
-#   folder ralated to Radiant project except the
-#   <adi_project_folder>/<project_name>/<project_name> folder.
-#   Also deletes the log file for Radiant project.
 #
 # * Note: The limitation for Propel Builder project is that it does not exit
 #   with error code no matter if the design was built or failed to,
