envolution [1] filed a deletion request for crdir [2]: Seems to not fit guidelines for AUR - the author seems to be learning how to write python and this unfortunately was not a useful concept to begin with. Essentially a shell wrapper to a python script that creates and cd's into $directory ( since they wanted the directory change to persist past the python interpreter exit they create, execute, and remove a shell script without any validation).
