[\-molecule \fIfile-or-directory\fP]
.SH DESCRIPTION
The \fImolecule\fP program draws several different representations of
Do not draw the bonds: instead, make the spheres for the atoms be
larger, for a "space-filling" representation of the molecule.
.TP 8
+.B \-shells
+Draw transparent electron shells around the atoms. This only works
+if bonds are also being drawn.
+.TP 8
+.B \-no\-shells
+Do not draw electron shells. This is the default.
+.TP 8
+.B \-shell\-alpha
+When drawing shells, how transparent to make them. Default 0.4.
+.TP 8
.B \-wire
Draw a wireframe rendition of the molecule: this will consist only of
single-pixel lines for the bonds, and text labels where the atoms go.
