# BashBlog, a simple blog system written in a single bash script

# README
#
#########################################################################################
#
# This is a very basic blog system
#
# Basically it asks the user to create a text file, then converts it into a .html file
# and then rebuilds the index.html and feed.rss.
#
# Comments are not supported.
#
# This script is standalone, it doesn't require any other file to run
#
# Files that this script generates:
#	- main.css (inherited from my web page) and blog.css (blog-specific stylesheet)
#	- one .html for each post
#	- index.html (regenerated each run)
# 	- feed.rss (regenerated each run)
#	- all_posts.html (regenerated each run)
# 	- it also generates temporal files, which are removed afterwards
#
# It generates valid html and rss files, so keep care to use valid xhtml when editing a post
#
# There are many loops which iterate on '*.html' so make sure that the only html files 
# on this folder are the blog entries and index.html and all_posts.html. Drafts must go
# into drafts/ and any other *.html file should be moved out of the way
#
# TODO instead of using a file for $content, use a variable to avoid disk writes
# TODO enclose all variables with quotes (thanks Durad)
# TODO use a tag for dates, and keep them in sync with the html files (thanks Durad)
