Finally I have taken the time to make a simple auto converter for the kindle reader. This will take HTML, PDF, LIT, PDB, and CHM files and convert them to .mobi. Saving the file anywhere you want, including directly to your usb connected kindle.
KindleGen is a command line tool used to build eBooks that can be sold through Amazon's Kindle platform. This tool is best for publishers and individuals who are familiar with HTML and want to convert their HTML, XHTML, XML (OPF/IDPF format), or ePub source into a Kindle Book.
