The origin of this program was to convert the file names of an erroneously zipped program. It used backslashes instead of forward slashes, so they unzipped as files only, no directories. You can use this program to take those files and fix the output into the correct result.
mkdir_backslash [flags] <input directory>
--no-delete: If the input and output location are the same, the input will be deleted, passing this flag prevents that.
-r, --recursive: Recursively descends subdirectories
-d <string>, --output-dir <string>, --output-directory <string>: Sets output location
-h, --help: Prints help message and exists
