/**
* Represents an AVR8 TDF. See the Targets::TargetDescription::TargetDescriptionFile close for more on TDFs.
*
* During the build process, we generate a JSON file containing a mapping of AVR8 target signatures to target
* description file paths. Bloom uses this mapping to find a particular target description file, for AVR8 targets,
* given a target signature. See directory "build/resources/TargetDescriptionFiles".
* The generation of the JSON mapping, is done by a PHP script:
* "build/scripts/CopyAvrPartFilesAndCreateMapping.php". This script is invoked via a custom command, at build time.
*
* For more information of TDFs, see src/Targets/TargetDescription/README.md
