I'll let Kovid do his own thing. Most of the fun was in the writing of it anyway
There's work to be done on the cleanup of TXT when exported from a PDF. What I have is readable so far but there's more I can do. I guess most are now reading LRF's on their readers?
The really annoying thing was the Author and Title embedded in the RTF's. I did have a method ages ago but that entailed hex editing all kinds of files - at least now it's eay for me.
