Metallurgy Go

A Golang command-line application for bulk converting images between PNG and JPG. The app finds all files with the extension given to --in flag and converts them to format given to --out flag. NOTE: This app is single-threaded, so the larger the file set given, the longer it will take. It will be fast, but not as fast as possible. Concurrent execution will be implemented in a future release.
