# (As the name implies) Based on the visual style of vim-powerline.
# Original prompt based on falconindy's, but that's been mostly replaced.

# Generates a prompt that looks roughly like
# >>> ~/path/to/src
# Where the first > (blue) represents a local tty, the second > (green)
# represents a non-su'd non-root tty, while the third > (magenta)
# represents a git repo, branch "master", untouched.
# These > expand and change color as desrcribed by the conditionals below.
# The xterm/rxvt window title is set as if it were a colorless console.
