xmailheaders is a mail notification utility that is based on the "mailbox" utility that's avilable on Solaris workstations. The idea is that it sits on your desktop somewhere, periodically polling the mail server/spool for new messages. New message headers are displayed as they come in. Supported mailbox formats are POP3, IMAPv4, and Unix mbox. SSL-based password authentication is also supported for POP and IMAP.
xmbmon is a monitoring program for motherboards which can monitor the CPU temperatures and the frequency of CPU cooling fans, etc. The package includes "mbmon", which can be used at the commandline to report the temperatures, voltages, and RPM (rounds per minute) of the fans, and "xmbmon", which displays the three temperatures and a core voltage as simple curves.
xmcd2make is a set of Perl scripts which support users of the gramofile recording, track splitting, and signal processing package. It consists of 3 userland tools: findtracks.pl (a command line interface to gramofile track detection), signalproc.pl (a command line interface to gramofile track splitting and signal processing), and xmcd2make.pl (a script that takes an xmcd file of song names and track timing files and creates a makefile). When the makefile is run, it splits the tracks, performs gramofile signal processing, and encodes the resulting tracks to Ogg Vorbis format with the correct song names and good tags.
xml-HTB is a tool for automatic generation of bash scripts that sets up HTB on Linux. It uses XML configuration files. It's easy to use, and features multiple depths of classes, configurable leaf, u32 and fw filters, and the ability to configure both the input and output interfaces at the same time.
xml2hostconf generates RPM packages, dhcpd.conf, pxelinux files, kickstart files, and HTML documentation with XSLT. It is a framework for central configuration and automatic installation of a Fedora/Redhat Linux network. Configuration files get shipped to the client computers by generated RPMs.
xml2sql-v is based on expat and is a quick and dirty solution to transform the content of any well-formed XML file into SQL INSERT statements such that you can postprocess the content of the XML data with SQL. The XML file is neither tested for correctness nor is it checked to contain anything reasonable. The insert statements will have the UTF-8 characterset but there are 3 more utilities (entityfix, latin1-utf8, and utf8-latin1), to fix broken HTML entities within the XML files, convert "forgotten" Latin1-Characters into proper XML entities, and convert the output back to Latin1 for easy insertion into the database.
