Kallimachos is a simple Web-based digital book-catalog intended for personal use. Books are indexed by title, author, translator, edition, genre, page number, and ISBN. You can insert a new book, enter the library, and search by any item. It also provides a system-info viewer. The installation is quick and simple, and the program has a user-friendly interface.
PHP Mobile Mail is aimed at mobile professionals who want to use their favorite MUAs (noteably pine or mutt) on their laptop, either in UNIX or Windows (under GNU Gygwin). This lets you work offline. It includes a mail_spooler program, which accepts the output of you MUA and spools (on, or offline). When connected, another process parses through the spool and sends your messages. It is also designed to "fake" using your REAL email address with free services like gmx.net, or mail.yahoo.com, when using their POP and SMTP servers, assuming you have a domain and account that you can control to this degree.
