The *.mdp file (it can have any name you want, grompp.mdp is just the 
default) contains all your options, like the number of steps, how
often you want to write data, electrostatics methods, etc. The only
way it is "optional" is that grompp will use default values for options
you don't include, so if you don't provide the file every single option
will have its default value. You probably don't want that :-)
