igorsk, I've written some perl wrapper scripts to feed HTML books into your HTML2LRF, mostly for Gutenberg HTML books, the thread is
here
Is there anyway to stop HTML2LRF from generating the front title page?
Also when running HTML2LRF you have to be in its directory for it to work otherwise it cannot find the DesignHorizontal.lrf file, noticed some code in the HTML2LRF.cpp to handle this but then later it is ignored and just looks in the current directory.
