Checked that the t2t is still valid and html should be automatically generated. Although there is some encoding issue with this file?
Thanks to "drbean" from the IRC channel for pointing this out!
+ Rename some txt2tags file from .txt to .t2t and remove abandoned .txt files. + Add program update_html that finds all .t2t documents and updates the corresponding .html file. It can be invoked with 'make html'. + Add style to some .html documents
