 paul@861      3 
The results of inspection for each module are written out to cache files, and
 
 paul@861      4 
these files should be able to provide all the information that is gathered
 
 paul@861      5 
during inspection without having to inspect the source code again. One minor
 
 paul@861      6 
benefit of using cached data, instead of having to parse and inspect the
 
 paul@861      7 
source code for a given module, is that of a slightly reduced processing time
 
 paul@861      8 
for the inspection activity. However, an arguably greater benefit is that of
 
 paul@861      9 
being able to see the outcome of the activity as a summary of accumulated
 
 paul@861     10 
data.
