Convert PML to LRF

The PML (Palm Markup Language) file is a format developed by Palm Inc for structuring eBooks, primarily used with eReader devices. It employs tags to format text, similar to HTML, and is compiled into a PDB file for display on Palm devices. Introduced to facilitate eBook reading on early handheld devices, PML played a key role in the evolution of digital book formats.

The LRF (Sony Portable Reader File) is a proprietary eBook format developed by Sony for its eReaders, such as the Sony Reader. It stores eBooks and textual content in a compressed binary format, including text, images, and pagination data. Introduced as part of the Broad Band eBook (BBeB) family, LRF files are unencrypted, whereas their encrypted counterparts use the LRX extension. The format became obsolete in 2010 when Sony transitioned to the EPUB format. Despite its obsolescence, LRF files can still be opened and converted using various software tools.
