/*****************************************************************************************
This file is a "mix-in" gradle script that individual gradle projects should include if they
have content for the Ghidra help system. A gradle project can include help support by adding
the following to its build.gradle file.
apply from: "$rootProject.projectDir/gradle/helpProject.gradle"
Clients can register dependencies on other help modules by using the
'helpPath' configuration, like so:
helpPath project(path: ":Base", configuration: 'helpPath')
This example will put into the 'helpPath' configuration the project path of
'Base', using the value of it's 'helpPath' configuration. This brings us to the next
point--'helpPath' gets updated when the jar file is built to include the path of
the generated jar file. This allows future clients of a given help module to get
the jar file path of that help module's output.
