-submodule config cache API
-==========================
-
-The submodule config cache API allows to read submodule
-configurations/information from specified revisions. Internally
-information is lazily read into a cache that is used to avoid
-unnecessary parsing of the same .gitmodules files. Lookups can be done by
-submodule path or name.
-
-Usage
------
-
-To initialize the cache with configurations from the worktree the caller
-typically first calls `gitmodules_config()` to read values from the
-worktree .gitmodules and then to overlay the local git config values
-`parse_submodule_config_option()` from the config parsing
-infrastructure.
-
-The caller can look up information about submodules by using the
-`submodule_from_path()` or `submodule_from_name()` functions. They return
-a `struct submodule` which contains the values. The API automatically
-initializes and allocates the needed infrastructure on-demand. If the
-caller does only want to lookup values from revisions the initialization
-can be skipped.
-
-If the internal cache might grow too big or when the caller is done with
-the API, all internally cached values can be freed with submodule_free().
-
-Data Structures
----------------
-
-`struct submodule`::
-
-	This structure is used to return the information about one
-	submodule for a certain revision. It is returned by the lookup
-	functions.
-
-Functions
----------
-
-`void submodule_free(struct repository *r)`::
-
-	Use these to free the internally cached values.
-
-`int parse_submodule_config_option(const char *var, const char *value)`::
-
-	Can be passed to the config parsing infrastructure to parse
-	local (worktree) submodule configurations.
-
-`const struct submodule *submodule_from_path(const unsigned char *treeish_name, const char *path)`::
-
-	Given a tree-ish in the superproject and a path, return the
-	submodule that is bound at the path in the named tree.
-
-`const struct submodule *submodule_from_name(const unsigned char *treeish_name, const char *name)`::
-
-	The same as above but lookup by name.
-
-Whenever a submodule configuration is parsed in `parse_submodule_config_option`
-via e.g. `gitmodules_config()`, it will overwrite the null_sha1 entry.
-So in the normal case, when HEAD:.gitmodules is parsed first and then overlayed
-with the repository configuration, the null_sha1 entry contains the local
-configuration of a submodule (e.g. consolidated values from local git
-configuration and the .gitmodules file in the worktree).
-
-For an example usage see test-submodule-config.c.
