This is a semiautomation tool written in nodewbkit. This tool allows copying of multiple files from one branch of a repository to other, so that users do not have to manually go into each subdirectory and copy the required file and then navigate to other branch and paste there. Instead, just provide a list of files need to be copied and Voilà, the job is done!
