This directory contains examples for the chem language.

On the displays, you can see rings consisting of several lines and
bonds (lines).  All points on rings and bonds that do not have a
notation mean a C atom (carbon) filled with H atoms (hydrogen) such
that the valence of 4 is satisfied.

For example, suppose you have just a single line without any
characters.  That means a bond.  It has two points, one at each end of
the line.  So each of these points stands for a C atom, the bond
itself connects these 2 C atoms.  To fulfill the valence of 4, each
points has to carry additionally 3 H atoms.  So the single empty bond
stands for CH3-CH3, though this combination doesn't make much sense
chemically.
