[OS X TeX] Installing Asymptote

[Richard Koch]

Folks,

I should have sent this message three days ago. I was paying attention, but not enough attention.

In the following message, William Adams is trying to use the Asymptote.engine in
TeXShop to process a sample TeX file with asymptote figures, also included in
TeXShop.

This is an error in the Asymptote engine included in TeXShop, which did not keep up
with changes made in the latest Asymptote program. To fix the problem,
edit the Asymptote engine, which is either in ~/Library/TeXShop/Engines 
or in ~/Library/TeXShop/Engines/Inactive/Asymptote.
The correct version is given below, and will shortly be in the version of TeXShop
on my web page.

The email thread continued with a suggestion by Herb Schulz to use latexmk with
Asymptote, and a remark by William Adams that latexmk worked. If you use Latexmk rather than this
Asymptote engine, Asymptote will not reprocess images when the document is
typeset again, unless the image changes.
