## VCC compiler backend discovery Utility
##
## Module to discover the path to the vcvarsall utility of a VCC compiler backend.
## The module supports discovery for either the latest recognizable version (default)
## or discovery of a specific VCC compiler backend version.
##
## This module can also produce a standalone command-line executable.
## It supports a `--help` command-line argument. Refer to its output for further
## documentation on the `vccdiscover` standalone command-line application.
