- * Description of submodule
+ * Return codes for submodule status.
  *
- * This record describes a submodule found in a repository.  There
- * should be an entry for every submodule found in the HEAD and for
- * every submodule described in .gitmodules.  The fields are as follows:
+ * A combination of these flags will be returned to describe the status of a
+ * submodule.  Depending on the "ignore" property of the submodule, some of
+ * the flags may never be returned because they indicate changes that are
+ * supposed to be ignored.
  *
- * - `name` is the name of the submodule from .gitmodules.
- * - `path` is the path to the submodule from the repo working directory.
- *   It is almost always the same as `name`.
- * - `url` is the url for the submodule.
- * - `oid` is the HEAD SHA1 for the submodule.
- * - `update` is a value from above - see gitmodules(5) update.
- * - `ignore` is a value from above - see gitmodules(5) ignore.
- * - `fetch_recurse` is 0 or 1 - see gitmodules(5) fetchRecurseSubmodules.
- * - `refcount` is for internal use.
+ * Submodule info is contained in 4 places: the HEAD tree, the index, config
+ * files (both .git/config and .gitmodules), and the working directory.  Any
+ * or all of those places might be missing information about the submodule
+ * depending on what state the repo is in.  We consider all four places to
+ * build the combination of status flags.
  *
- * If the submodule has been added to .gitmodules but not yet git added,
- * then the `oid` will be zero.  If the submodule has been deleted, but
- * the delete has not been committed yet, then the `oid` will be set, but
- * the `url` will be NULL.
+ * There are four values that are not really status, but give basic info
+ * about what sources of submodule data are available.  These will be
+ * returned even if ignore is set to "ALL".
+ *
+ * * IN_HEAD   - superproject head contains submodule
+ * * IN_INDEX  - superproject index contains submodule
+ * * IN_CONFIG - superproject gitmodules has submodule
+ * * IN_WD     - superproject workdir has submodule
+ *
+ * The following values will be returned so long as ignore is not "ALL".
+ *
+ * * INDEX_ADDED       - in index, not in head
+ * * INDEX_DELETED     - in head, not in index
+ * * INDEX_MODIFIED    - index and head don't match
+ * * WD_UNINITIALIZED  - workdir contains empty directory
+ * * WD_ADDED          - in workdir, not index
+ * * WD_DELETED        - in index, not workdir
+ * * WD_MODIFIED       - index and workdir head don't match
+ *
+ * The following can only be returned if ignore is "NONE" or "UNTRACKED".
+ *
+ * * WD_INDEX_MODIFIED - submodule workdir index is dirty
+ * * WD_WD_MODIFIED    - submodule workdir has modified files
+ *
+ * Lastly, the following will only be returned for ignore "NONE".
+ *
+ * * WD_UNTRACKED      - wd contains untracked files

+ * Description of submodule
+ *
+ * This record describes a submodule found in a repository.  There should be
+ * an entry for every submodule found in the HEAD and index, and for every
+ * submodule described in .gitmodules.  The fields are as follows:
+ *
+ * - `owner` is the git_repository containing this submodule
+ * - `name` is the name of the submodule from .gitmodules.
+ * - `path` is the path to the submodule from the repo root.  It is almost
+ *    always the same as `name`.
+ * - `url` is the url for the submodule.
+ * - `tree_oid` is the SHA1 for the submodule path in the repo HEAD.
+ * - `index_oid` is the SHA1 for the submodule recorded in the index.
+ * - `workdir_oid` is the SHA1 for the HEAD of the checked out submodule.
+ * - `update` is a git_submodule_update_t value - see gitmodules(5) update.
+ * - `ignore` is a git_submodule_ignore_t value - see gitmodules(5) ignore.
+ * - `fetch_recurse` is 0 or 1 - see gitmodules(5) fetchRecurseSubmodules.
+ * - `refcount` tracks how many hashmap entries there are for this submodule.
+ *   It only comes into play if the name and path of the submodule differ.
+ * - `flags` is for internal use, tracking where this submodule has been
+ *   found (head, index, config, workdir) and other misc info about it.
+ *
+ * If the submodule has been added to .gitmodules but not yet git added,
+ * then the `index_oid` will be valid and zero.  If the submodule has been
+ * deleted, but the delete has not been committed yet, then the `index_oid`
+ * will be set, but the `url` will be NULL.
