#########################################################################################
|
|
#
|
|
# 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 supported via external service (Disqus).
|
|
# Markdown syntax is supported via third party library (e.g. Gruber's Markdown.pl)
|
|
#
|
|
# 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
|
|
# - one tag_*.html file for each tag
|
|
# - index.html (regenerated each run)
|
|
# - feed.rss (idem)
|
|
# - all_posts.html (idem)
|
|
# - all_tags.html (idem)
|
|
# - 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 not to manually put other
|
|
# html files on this folder.
