BARF - emit HTML

DESCRIPTION
	BARF utilizes rc(1) and command line tools to compile a structured
	directory of files into a single page of HTML. Tagging and RSS 2.0
	feeds have been implemented.

SETUP
	To enable BARF, add:

		conf_enable_barf

	to _werc/config under the site root.

	To configure BARF, copy or create the following files under the site
	root (example files have been included in this distribution):

	_werc/barf/config
		A list of variables that control various site options:

			barf_type=paste # blog, image, log, paste
			posts_per_page=10
			show_ascending=0
			show_footer=0
			show_header=0
			show_sidebar=0
			require_login=0 # if not logged in, redirect to /login
			allow_anon=1 # allow posts without logging in
			show_disqus=0 # include disqus comments template
					# from _werc/barf/disqus

	_werc/barf/footer
		HTML or markdown that will appear as the foot of
		the BARF content area.

	_werc/barf/header
		HTML or markdown that will appear at the head of
		the BARF content area.

	_werc/barf/sidebar
		HTML or markdown that will appear on one side of
		the BARF content area.

	Finally, sample stylesheets are provided in the directory
	pub/. Copy any of these to _werc/pub/style.css to try
	them out.

POSTS
	Posts are stored in the directory src/ relative to the
	site root.

	Directory names in src/ that do not match the regular
	expression ^[0-9]*$ will not be included in the listing of
	posts that are displayed in the browser. However, such
	directories are still accessible when called directly via
	an appropriately constructed URL.

	A post's directory contains the following files and
	directories (an example post's directory has been
	included in this distribution):

		body
		date
		img/
		link
		tags/
		title

	The img/ directory contains images uploaded to the
	image board, including the original image and a
	thumbnail version, resized to no greater than 500
	pixels wide and 600 pixels tall.

	The tags/ directory contains one empty file named
	for each tag associated with the post.

	The site root contains a file named tags that is compr-
	ised of an index of the tags associated with each post.
	This index is consulted when searching for a given tag in
	the web browser.

UTILS
	bin/gf
		Parse Livejournal and Tumblr RSS feeds into
		BARF posts. (Abandoned, may no longer work.)
	bin/gk
		Create a list of known tags in the site root in
		a file named known_tags.
	bin/gr
		Parse Google Reader bundles into BARF posts.
	bin/gt
		Create an index of tags in the site root in a file
		named tags.

	For more information on these tools, read the source.

ADMIN
	Any tool that can create, alter, or delete flat files
	and directories is sufficient to administer a BARF.

	Web-based login and administration utilizes werc's
	built-in user authentication:

		http://domain.com/login

	After login, links to edit and delete will appear in
	each post's meta data.

	Web-based administration requires that the src/
	directory and its sub-directories are writable by
	the web server process.

REQUIREMENTS
	Unix
		Plan9port or 9base are required. Site type
		image requires ImageMagick and curl. Site
		type url also requires curl if the user employs
		the option to download remote URLs. These
		utilities may be swapped out for others by
		altering the source.

EXAMPLES
	blog
		http://read.stanleylieber.com
		RSS feeds are converted by the utility rrss[0]
		and stored as individual blog posts.
	image
		http://img.stanleylieber.com
		Hybrid public/private image board. Requires
		standard werc authentication to post, but all
		posts are visible to the public.
	paste
		http://okturing.com
		Public pastebin. No authentication required
		to post.
	url
		http://url.stanleylieber.com
		Private index of URL bookmarks, similar
		in functionality to the old delicious.com.
		(In fact, most of the index was imported
		from delicious.)

BUGS
	On Plan 9, if the web server process is run as user
	none (typically the case), directories used for entering
	posts or uploading/downloading files from the browser
	must be set world writable. This could prove problematic
	on multiuser systems.
