Hi,
I'm in need of help to get the example as described in the MetaFun
manual running, because I want to use text around a path!
So, I started reading the chapter about 'Typesetting in METAPOST' and
wanted to try the examples as given in that chapter, but without succes!
The problem seem to be the MPtoks macro. According to the text in this
chapter this low level macro (and MPbox and appendtoks) are already
defined, but are they really?
The version of context minimals I use at the moment is:
MTXrun | current version: 2011.01.18 19:34
Any suggestions are very much welcomed! Thanks in advance!
Regards,
Gerard
