# Usage:
# Just add pip to your installed plugins.

# If you would like to change the cheeseshops used for autocomplete set
# ZSH_PIP_INDEXES in your zshrc. If one of your indexes are bogus you won't get
# any kind of error message, pip will just not autocomplete from them. Double
# check!
#
# If you would like to clear your cache, go ahead and do a
# "zsh-pip-clear-cache".
