4 The merge API helps a program to reconcile two competing sets of
5 improvements to some files (e.g., unregistered changes from the work
6 tree versus changes involved in switching to a new branch), reporting
7 conflicts if found. The library called through this API is
8 responsible for a few things.
10 * determining which trees to merge (recursive ancestor consolidation);
12 * lining up corresponding files in the trees to be merged (rename
13 detection, subtree shifting), reporting edge cases like add/add
14 and rename/rename conflicts to the user;
16 * performing a three-way merge of corresponding files, taking
17 path-specific merge drivers (specified in `.gitattributes`)
23 * `mmbuffer_t`, `mmfile_t`
25 These store data usable for use by the xdiff backend, for writing and
26 for reading, respectively. See `xdiff/xdiff.h` for the definitions
27 and `diff.c` for examples.
29 * `struct ll_merge_options`
