Convert PDB EBOOK to CTX

The PDB (Palm Database) file extension, associated with PalmDoc eBooks, is a format used for storing eBooks on Palm OS devices. Originating from AportisDoc, PalmDoc files are plain ASCII text compressed using Run-Length Encoding (RLE) to save memory space. These files are decompressed on the fly by PalmDoc readers, facilitating efficient storage and quick access. The PDB format, with its Creator ID and Type attributes, ensures compatibility across various Palm applications, making it a versatile choice for eBook distribution on Palm devices.

The CTX file extension is associated with the ConTeXt Markup Language, a typesetting system used for creating structured documents. It is primarily utilized for document layout and design, offering advanced typographic features and flexibility. ConTeXt was developed by Hans Hagen and Ton Otten in the early 1990s as an alternative to LaTeX, aiming to provide a more integrated and user-friendly approach to document preparation. The CTX file format is part of this system, enabling the creation of high-quality, publication-ready documents.
