Jekyll post

jekyll-post

#!/usr/bin/python

"""
jekyll-post - this is a simple script that will create and initialize a new
Jekyll post file. The default is a markdown file (.md) and the yaml options
listed below will be part of the initialization.

jekyll-post [-w] [-d date] [title]

title   the title of the post wrapped in quotes, e.g. "post title here"
-D      the directory (relative or absolute) that the file should be written to.
-d      the default date is today's date or this option can be used to specify
        a date. The date must be specified in the format YYYY-MM-DD.
-n      the name for the post file instead of using the automatically generated one.
-t      the tags that should be added to the yaml portion of the file separated
        by spaces and the whole thing wrapped in quotes.
-w      this optional flag will signal the file to be opened for writing in vi.
