-# Installation
-# ------------
-#
-# 1. Add this script to a directory on your $fpath:
-# fpath[1,0]=~/.zsh/completion/
-# mkdir -p ~/.zsh/completion/
-# cp scripts/zsh_completion/_bazel ~/.zsh/completion
-#
-# 2. Optionally, add the following to your .zshrc.
-# zstyle ':completion:*' use-cache on
-# zstyle ':completion:*' cache-path ~/.zsh/cache
-#
-# This way, the completion script does not have to parse Bazel's options
-# repeatedly. The directory in cache-path must be created manually.
-#
-# 3. Restart the shell
-#
-# Options
-# -------
-# completion:init:bazel:* cache-lifetime
-# Lifetime for the completion cache (if turned on, default: 1 week)
