*
* ## Libraries
*
* [Each library](pages.html) helps to untangle the code by grouping similar
* functions and reducing dependencies.
*
* The goal is that each library is:
* - Self-contained (it may rely on other libraries)
* - Independently testable (i.e. without using NeoMutt)
* - Fully documented
* - Robust
*
* Libraries:
* @ref lib_address, @ref lib_alias, @ref lib_attach, @ref lib_autocrypt,
* @ref lib_bcache, @ref lib_browser, @ref lib_color, @ref lib_compmbox,
* @ref lib_compose, @ref lib_compress, @ref lib_config, @ref lib_conn,
* @ref lib_convert, @ref lib_core, @ref lib_email, @ref lib_enter,
* @ref lib_envelope, @ref lib_gui, @ref lib_hcache, @ref lib_helpbar,
* @ref lib_history, @ref lib_imap, @ref lib_index, @ref lib_maildir,
* @ref lib_mbox, @ref lib_menu, @ref lib_mixmaster, @ref lib_mutt,
* @ref lib_ncrypt, @ref lib_nntp, @ref lib_notmuch, @ref lib_pager,
* @ref lib_pattern, @ref lib_pop, @ref lib_postpone, @ref lib_progress,
* @ref lib_question, @ref lib_send, @ref lib_sidebar, @ref lib_store.
*
* ## Miscellaneous files

* These file form the main body of NeoMutt.

*
* ## Building these Docs
*
* The config for building the docs is in the main source repo.
*
* Everything possible is turned on in the config file, so you'll need to
* install a few dependencies like `dot` from the graphviz package.
*
* ## Installing the Docs
*
* These docs aren't in the main website repo -- they weigh in at 100MB.
* Instead, they're stored in the [code repo](https://github.com/neomutt/code)
