# This script host your gists as local Github repo
# It works with jq and curl, which are easy to get in most cases
#
# Use the following commands to manage your gists:
#
# * update your gists list with Github API
# gist [update | u]
#
# * list your gists with format: [number] [url] [file_num] [comment_num] [short description]
# gist
#
# * clone gist repos which are not in local
# gist [sync | s]
#
# * Go to local gist repo
# gist <number_of_gist_in_list>
#
# * create a new gist with a file and description
# gist [create | c] <filename> "<description>"
#
# * show the detail of a gist
# gist [detail | d] <number_of_gist_in_list>
#
# * edit a gist description
# gist [edit | e] <number_of_gist_in_list>
#
# * delete a gist
# gist [delete | D] <number_of_gist_in_list>
#
# * clean removed gists in local
# gist [clean | C]
