Re: Macro that calls external program

[Josh <jnfo-d@grauman.com>]

Thanks! This is very helpful.

I have a related question. How can I run an external program right before 
Export that takes as input the current buffer and prints out to stdout an 
updated version of the org file that then is exported? Basically I want to 
pipe the org file through a filter that is an external program before it 
is exported.

Thanks in advance!
