Re: Macro that calls external program

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

Thanks Ken.

Yes, at first I was trying to accomplish my task with Macros, but after 
finding out that I could run the whole Org file through a pre-filter, I 
realized that this would be a much cleaner and easier way rather than 
having multiple types of macros or code blocks. So now I'm trying to 
figure out how to attach an external program to 
`org-export-before-parsing-hook' or `org-export-before-processing-hook' to 
pipe the entire Org file through...
