Dear Richard,

Thanks for your response.

Wow, thanks!  I'm humbled to make a useful feature request.  Being  
able to write custom engines makes TeXShop more than just a TeX IDE.   
Suddenly you have a text editor with pluggable processor interface.

Here's another application:  For web pages, I don't write HTML  
because I get distracted by styling and balancing tags and all that.   
I write ReStructured Text [1] and run python scripts which transform  
it to well-formed XHTML with nice class settings so it's easy to  
write CSS for styling.

Currently, I use makefiles, edit in emacs, and run the makefiles  
within emacs to compile and view the result.  But half the time I hit  
command-T instead, because it's the same process: write text, then  
process.  If TeXShop could be configured by the user to "typeset" RST  
files, all you'd need is another engine instead of a makefile.

Or povray [2], a raytracer for 3D graphics....the list goes on!

That's probably better.  My experience with using open on the command  
line is that if the file is already open by the application, but the  
file has changed since the original open, the original version is  
still shown.  At least, this is what I saw in Preview.  But I think  
they fixed that in new versions of Preview?

Anyway, thanks again.
