But, Hobby wrote
``Some recently-added features of the languages are documented only
in a separate report.''
Drawing Graphs with MetaPost, AT&T Bell Laboratories Computing
Science Technical Report 164, 1992.

What about moving the whole Appendix B ``New Languague Features''
from the Technical Report 164 to the mpost user manual?
