| /**
 | |
|  * 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
 | |
|  * -----
 | |
|  *
 | |
|  * 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().
 | |
|  *
