/** @mainpage
 *  Welcome to the API documentation for ZNC.
 *
 *  To write your own module, you should start with writing a new class which
 *  inherits from CModule. Use #MODCONSTRUCTOR for the module's constructor and
 *  call #MODULEDEFS at the end of your source file.
 *  Congratulations, you just wrote your first module. <br>
 *  For global modules, the procedure is similar. Instead of CModule you inherit
 *  from CGlobalModule. The two macros are replaced by #GLOBALMODCONSTRUCTOR and
 *  #GLOBALMODULEDEFS.
 *
 *  If you want your module to actually do something, you should override some
 *  of the hooks from CModule. These are the functions whose names start with
 *  "On". They are called when the associated event happens.
 *
 *  Feel free to also look at existing modules.
