* NAME
* prunebinaries.js
*
* DESCRIPTION
* Removes pre-built binaries for all other architectures.
* This can be used to reduce the footprint of a node-oracledb install.
*
* USAGE
* Invoke this from the top level directory.
* After an 'npm install oracledb' installs pre-built binaries, this file
* can be run with 'npm run prune [all]'.
* 'npm run prune' will keep only the binary files for the platform where
* the application using node-oracledb is being run.
* Passing the optional 'all' parameter deletes all binary files, so that
* only Thin mode will be available.
*
