Help: Command

This is a parent class for some of the defining objmanip commands
since they tend to have some more variables to define new objects.

Each object definition can have several components. First is
always a name, followed by an optional alias list and finally an
some optional data, such as a typeclass or a location. A comma ','
separates different objects. Like this:

name1;alias;alias;alias:option, name2;alias;alias ...

Spaces between all components are stripped.

A second situation is attribute manipulation. Such commands
are simpler and offer combinations

objname/attr/attr/attr, objname/attr, ...
