zblog hook reference

0. Introduction

  To improve zblogs flexibility, I added function calls to zblog I call hooks.
  These functions are empty by default. To get a list of available hooks, you
  may use the 'bin/genhooks.sh' script.
  That script will list all functions that are called as hooks in zblog along
  with a list of the arguments that are given to it, if any.


1. Naming

  The names of the hooks reflect their position in zblog. Thus you can see when
  a hook will be called by interpreting its name.
