the call graph[1] generator counted 66 functions. they appear to be  
split 1/3 - 2/3 between configuration and computation. that leaves  
about 44, which is about fifty percent of the pre 1.3 asdf function  
count.

what requirement does that support? in particular, it would help to  
record in the manual section on "output translation implementation"  
why the process translates twice and what the respective realms mean.
