description         A vector graphics language
long_description    Asymptote is a powerful descriptive \
                    vector graphics language that provides a natural \
                    coordinate-based framework for technical drawing. \
                    Labels and equations are typeset with LaTeX, for \
                    high-quality PostScript output.

#
# The hierarchy of dependencies goes as:
# - texlive-latex-recommended [common, bin, basic, latex]
# - texlive-latex             [common, bin, basic]
# - texlive-basic             [common, bin]
#
# But then asy also supports luatex, context, etc.
