 Data structures and editor things forrepository inspection.As it turns out, the svn_repos_replay2(), svn_repos_dir_delta2() and svn_repos_begin_report3() interfaces can be extremely useful for examining the repository, or more exactly, changes to the repository
 Dumping, loading and verifying filesystem dataThe filesystem 'dump' format contains nothing but the abstract structure of the filesystem – independent of any internal node-id schema or database back-end
 String handling
 APR Array Compatibility Helper MacrosThese macros are provided by APR itself from version 1.3
 APR Hash Table HelpersThese functions enable the caller to dereference an APR hash table index without type casts or temporary variables
 Dirent fieldsIt is sometimes convenient to indicate which parts of an svn_dirent_t object you are actually interested in, so that calculating and sending the data corresponding to the other fields can be avoided
 Keyword definitionsKeyword substitution
 Node location segment reporting.
