A ZSH theme optimized for people who use:
- Solarized
- Git
- Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

# This script prints a bell character when a command finishes | |
# if it has been running for longer than $zbell_duration seconds. | |
# If there are programs that you know run long that you don't | |
# want to bell after, then add them to $zbell_ignore. | |
# | |
# This script uses only zsh builtins so its fast, there's no needless | |
# forking, and its only dependency is zsh and its standard modules | |
