    1 * SRFI 173: Hooks
    2 ** Abstract
     1= SRFI 173: Hooks
     2== Abstract
    33This library describes a mechanism known as hooks. Hooks are a certain kind of extension point in a program that allows interleaving the execution of arbitrary code with the execution of the program without introducing any coupling between the two.

    55For more information see: [[https://srfi.schemers.org/srfi-173/srfi-173.html|SRFI 173: Hooks]]
    6 ** Rationale
     6== Rationale
    77The use of hooks is pervasive in GNU Emacs and many other programs that offer some "plugin" mechanism that is built on top a facility similar to what this library offers.
    88
    99While building programs, there is a need to offer extension points to allow the user to extend and customize the execution of the program in way that avoids coupling. This library wants to help with that.

     69== Implementation Notes
    7070The reference implementation from SRFI-173 was used verbatim, with the exception of a single call to =assume= from [[https://srfi.schemers.org/srfi-145/srfi-145.html|SRFI 145]], which was replaced with =assert=.
    71 ** Acknowledgements
     71== Acknowledgements
    7272This specification is based on the GNU Guile module called [[https://www.gnu.org/software/guile/manual/html_node/Hooks.html#Hooks|hook]].
