+A simple static blog generator in Lua, without external dependencies.
+Tested on Lua 5.1+
+
+NOTE: Things are not being escaped yet, expect broken stuff, take care.
+
+Put the data in htroot into your destination folder. Then run ./generate <destination>.
+
+Edit data/setting/sub_path.txt to point to the right sub-directory on your web server, otherwise the links will be broken.
+
+How to make a post:
+* Create this file: data/post/YYYYMMDD-HHMM_My post/content.html
+* Add the post to the entry list (data/post/entries.txt), like so:
+YYYYMMDD-HHMM_My post
+(Sorting does not matter)
+
+How to change the layout/style:
+* Edit data/setting/page.html for the page layout and style
+* Edit data/setting/post.html for the post layout (don't put style here)
+* You can put $$VARIABLES$$ inside these html files, to reference certain things
+
