+--standalone::
+ Limit checks to the contents of GIT_OBJECT_DIRECTORY
+ ($GIT_DIR/objects), making sure that it is consistent and
+ complete without referring to objects found in alternate
+ object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES,

+
+--full::
+ Check not just objects in GIT_OBJECT_DIRECTORY
+ ($GIT_DIR/objects), but also the ones found in alternate
+ object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES,
+ and in packed GIT archives found in $GIT_DIR/objects/pack
+ and corresponding pack subdirectories in alternate
+ object pools; cannot be used with --standalone.
+
+--strict::
+ Enable more strict checking, namely to catch a file mode
+ recorded with g+w bit set, which was created by older
+ versions of GIT. Existing repositories, including the
+ Linux kernel, GIT itself, and sparse repository have old
+ objects that triggers this check, but it is recommended
+ to check new projects with this flag.
