The issue I have with this is simple....

Escape data for make.  Obviously this is acceptable ;)
Then escape the data for shell/printf/ect.  Here is the big conundrum, 
it's way to difficult to think about how this get's unwrapped and to 
debug the results.

Is there a simpler way that I'm overlooking?  Obviously I'm overlooking 
having a make file and then several data files with out using here 
documents....  That's not the solution I'm looking for, I'd have to use 
what I have instead.
