Whip

The whip tool was born with the mission to simplify the integration of the actions to follow after the installation of a package and/or to manage OS checks.

It uses YAML to handle the triggers/hooks to run.

In the Gentoo/Funtoo worlds this means for the post-install phase to execute the commands now available inside the ebuilds in the postinst section.

Specifications

Hereinafter, an example of the YAML content of the actions to run:
