%description
An interface to the powerful and fairly complete computer algebra system
'Maxima'. It can be used to start and control 'Maxima' from within R by
entering 'Maxima' commands. Results from 'Maxima' can be parsed and
evaluated in R. It facilitates outputting results from 'Maxima' in 'LaTeX'
and 'MathML'. 2D and 3D plots can be displayed directly. This package also
registers a 'knitr'-engine enabling 'Maxima' code chunks to be written in
'RMarkdown' documents.
