I've been working on a "lrf2pdf" tool, in java, starting from iText (Lowagie) and LRFParse (scotty1024). Actually transformation support images an TOC from lrf, and also dumps the whole lrf to an XML file. Usage is:
java -Xms100M -jar dumplrf.jar directory [-z zipfile] [-xml|-pdf]
it searches recursively 'directory' for lrf file names in 'title - author.lrf' format, and creates pdf in the same place (if -pdf is specified) or builds 'zipfile' if '-z' is also specified.
Hope you like it.
