The first bug is that we will repeatedly write out the result of a customized raw definition to the filesystem, even when a cache entry already exists. The second bug is that caching these definitions doesn't actually work (the cache entry is written but never used.) A new API for retrieving raw definitions permits the user to take advantage of caching. Signed-off-by: Edward Z. Yang <ezyang@mit.edu>
