Same here! Except I don't know accounting. I wish the XCmdFunc.c (the 
API) had some comments in it. The readme for the externals speaks as if 
there is a published API that it conforms to, but I can't find it 
anywhere.

I have managed to scrape a working external together, revclips, but it 
doesn't use any advanced features like array and image twiddling.

Unrelated but:
After nearly going insane trying to write a string replacement function 
using the standard C string library functions, I found this cool 
library. It's small, safe and easy to use and I hope I attempt to use 
strtok() again. http://bstring.sourceforge.net/
