Detailed Description

Trait class used to search the on-disk hash table containing all of the header search information.

The on-disk hash table contains a mapping from each header path to information about that header (how many times it has been included, its controlling macro, etc.). Note that we actually hash based on the size and mtime, and support "deep" comparisons of file names based on current inode numbers, so that the search can cope with non-normalized path names and symlinks.
