Test2::Manual::Tooling::Plugin::ToolCompletes \- How to add behaviors that occur
when a tool completes work.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This tutorial helps you understand how to add behaviors that occur when a tool
is done with its work. All tools need to acquire and then release a context,
for this tutorial we make use of the release hooks that are called every time a
tool releases the context object.
