-## Mathematical structures
-
-MathComp-Analysis adds mathematical structures on top of MathComp's ones.
-The following inheritance diagram displays the resulting hierarchy as of version 1.1.0
-(excluding most MathComp structures).
-The structures introduced by MathComp-Analysis are highlighted.
-(See `topology.v`, `normedtype.v`, `reals.v`, `measure.v`.)
