%description
An R interface to the Chemistry Development Kit, a Java library for
chemoinformatics. Given the size of the library itself, this package is
not expected to change very frequently. To make use of the CDK within R,
it is suggested that you use the 'rcdk' package. Note that it is possible
to directly interact with the CDK using 'rJava'. However 'rcdk' exposes
functionality in a more idiomatic way. The CDK library itself is released
as LGPL and the sources can be obtained from <https://github.com/cdk/cdk>.
