Is there a package with LaTeX symbols for the poset relations "covers" and "is covered by", as seen in http://en.wikipedia.org/wiki/Covering_relation? I've tried creating ⋅> and <⋅ symbols on my own using \cdot, <, and >, but the spacing between the two symbols tends to vary, as does the surrounding space, in ways that don't look good.
