GNU grep is based on a fast lazy-state deterministic matcher (about twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper search for a fixed string that eliminates impossible text from being considered by the full regexp matcher without necessarily having to look at every character. The result is typically many times faster than Unix grep or egrep.
KBACKUP is intended for handling of backups no matter whether they reside on disk or tape or even in files. As most other backup programs available today are either confusing the user with lots of long command line options, or user friendly but not powerful at all, the aim behind writing KBACKUP was to provide a user friendly yet powerful backup program. It is also intended to be kept compatible to existing and well proven archive formats, so you can restore your archives even if you should not have KBACKUP around anymore.

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.
