# Autoblock
#
# Automatically formats story blocks into nice HTML.  Supports a
# number of natural block-formatting modes, including paragraph,
# quote, and code.  
#
# WARNING ******
#
# I use this plugin to format the articles on my own sites, but
# it is still a work in progress!  Please report bugs and limitations
# (and I will fix them promptly).
#
# Formats:
# * Ignores most existing blocks
# * Formats paragraphs separated with blank lines
# * Formats code-blocks preceeded by a :: found on a blank line
# * Formats block-quotes indented with spaces
# * Other types will be added as I need them
