+/**
+ * Automatic CI process for generating new vcpkg releases.
+ * Based loosely on RealTimeChris's shell script version.
+ * 
+ * This updates the content of ./vcpkg directory within the DPP
+ * repository on the master branch, which can then be diffed into
+ * the microsoft/vcpkg master branch to build a PR for the new
+ * release.
+ * 
+ * The procedure for this is:
+ * 
+ * 1) Generate various configuration files and put them into the
+ *    systemwide vcpkg installation inside the CI container
+ * 2) Attempt to build the package from the release tag,
+ *    this will fail due to invalid SHA512 sum and return the
+ *    correct SHA512 sum in the error output. Inability to get the
+ *    SHA512 sum here will return nonzero from the script, failing
+ *    the CI action.
+ * 3) Capture the SHA512 from the error output, switch to master
+ * 4) Copy the correct configuration into both the systemwide
+ *    vcpkg install in the container, and into the vcpkg directory
+ *    of master branch.
+ * 5) Rerun the `vcpkg install` process again to verify it is working.
+ *    A build failure here will return a nonzero return code from
+ *    the script, failing the CI action.
