#!zsh
# This script arranges some percol-related userful zle-widgets and
# commands
#
# To use this script, put a following line into your .zshrc
#
# source PATH_TO_THIS_FILE
#
# Then, you can bind percol's zle-widgets to some key, by calling
# bindkey.
#
# bindkey '^R' percol_select_history
#
# Here is the list of zle-widgets provided by this script.
#
# * percol_select_history
# * percol_cd_sibling
# * percol_cd_upper_dirs
# * percol_cd_bookmark
# * percol_cd_repository
# * percol_insert_bookmark
# * percol_insert_ls
#
# And this script also provides following commands.
#
# * ppgrep
# * ppkill
#
# Enjoy!
