"deisctl install" looks for unit files in these directories, in this order:
- the $DEISCTL_UNITS environment variable, if set
- $HOME/.deis/units
- /var/lib/deis/units
Usage:
deisctl refresh-units [-p <target>] [-t <tag>]
Options:
-p --path=<target> where to save unit files [default: $HOME/.deis/units]
-t --tag=<tag> git tag, branch, or SHA to use when downloading unit files
[default: master]
