Beside the python dependencies defined in [requirements.txt](https://github.com/deadc0de6/dotdrop/blob/master/requirements.txt), dotdrop depends on following tools:
* `file`
* `diff`
* `mkdir`
* `git` (for the entry point script [dotdrop.sh](https://github.com/deadc0de6/dotdrop/blob/master/dotdrop.sh))
* `readlink` or `realpath` (for the entry point script [dotdrop.sh](https://github.com/deadc0de6/dotdrop/blob/master/dotdrop.sh))

For MacOS users, make sure to install `realpath` (part of `coreutils`) through [homebrew](https://brew.sh/).
