+\section{Introduction}
+This package concerns mathematical drawings arising in representation theory.
+The purpose of this package is to ease drawing of rank 2 root systems, with Weyl chambers, weight lattices, and parabolic subgroups, mostly imitating the drawings of Fulton and Harris \cite{Fulton.Harris:1991}.
+We use definitions of root systems and weight lattices as in Carter \cite{Carter:2005} p. 540--609.

+Type \verb!\wt{x}{y}! to get a weight at position \((x,y)\) (as measured in a basis of \emph{fundamental weights}).
+Type \verb!\wt[multiplicity=n]{x}{y}! to get multiplicity \(m\).
+Add an option: \verb!\wt[Z]{x}{y}{m}! to get \verb!Z! passed to TikZ.

+\section{Coordinate systems}
+
+The package provides three coordinate systems: hex, square and weight.
+Above we have seen the weight coordinates: a basis of fundamental weights.
+We can also use weight coordinates like
+\[
+\verb!\draw \weight{0}{1} -- \weight{1}{0};!
+\]
+The square system, used like \verb!\draw (square cs:x=1,y=2) circle (2pt);!, is simply the standard Cartesian coordinate system measured so that the minimum distance between weights is one unit.
+The hex coordinate system has basis precisely the fundamental weights of the \(A_2\) lattice.
+We can use the hex system in drawing on the \(A_2\) or \(G_2\) weight lattices, as below, as they are the same lattices.
