Overview

Package union offers a simple http.FileSystem that can unify multiple filesystems at various mount points. Copied from https://github.com/shurcooL/httpfs/blob/master/union/union.go due to import issues

/fs0/zzz-last-file.txt
/fs1
/fs1/folderA
/fs1/folderA/file1.txt
/fs1/folderA/file2.txt
/fs1/folderB
/fs1/folderB/folderC
/fs1/folderB/folderC/file3.txt
/fs1/not-worth-compressing-file.txt
