+ -e : Dump Vars and Rules on error\n\
+ -w : Print additional information\n\
+ -p : Prints the variables and the rules before building\n\
+ -n : Only prints the commands, but does not execute them\n\
+ -l : Print parser debug information\n\
+ -d : Print the dependency checking\n\
+ -CD : Do circular dependency checking (targets depending on itself)\n\
+ -m : Create md5 database in md5.database in start directory. \n\
+ -b : Print build tree. \n\
+ -D : Print all double defined rules (even if commands are the same) \n\

+It is adviced during creation of makefiles to use mhmake_dbg. It has additional\n\
+debugging options and does some extra error checking.\n\
+For a description of the additional options: run mhmake_dbg -h\n\
