Substitute /bin/bash with /bin/tcsh or /bin/zsh as appropriate.
## Optional Dependencies
In order to generate completions from man pages compressed with either lzma or xz, you may need to install an extra Python package.
Python versions prior to 2.6 are not supported. For Python versions 2.6 to 3.2 you need to install the module `backports.lzma`. How to install it depends on your system and how you installed Python. Most Linux distributions should include it as a package named `backports-lzma` (or similar). From version 3.3 onwards, Python already includes the required module.
