/**
* @file
* @brief support for connected components
* @ingroup public_apis
*
* **libpack** supports the use of connected components
* in the context of laying out graphs using other graphviz libraries.
* One set of functions can be used to take a single graph and break it
* apart into connected components.
* A complementary set of functions takes a collection of graphs
* (not necessarily components of a single graph) which have been laid
* out separately, and packs them together.
*
* As this library is meant to be used with `libcommon`, it relies on the
* @ref Agraphinfo_t, @ref Agnodeinfo_t and @ref Agedgeinfo_t used in
* that library.
*
* [man 3 libpack](https://graphviz.org/pdf/pack.3.pdf)
