small to large enterprise environments using standards-based
internet mail technologies.

A full Cyrus IMAP implementation allows a seamless mail and bulletin
board environment to be set up across multiple servers. It differs from
other IMAP server implementations in that it is run on "sealed"
servers, where users are not normally permitted to log in and have no
system account on the server. The mailbox database is stored in parts
of the filesystem that are private to the Cyrus IMAP server. All user
access to mail is through software using the IMAP, POP3 or KPOP
protocols. It also includes support for virtual domains, NNTP,
mailbox annotations, and much more. The private mailbox database design
gives the server large advantages in efficiency, scalability and
administratability. Multiple concurrent read/write connections to the

The diff command compares files line by line. Diffstat reads the
output of the diff command and displays a histogram of the insertions,
deletions and modifications in each file. Diffstat is commonly used
to provide a summary of the changes in large, complex patch files.

Install diffstat if you need a program which provides a summary of the
diff command's output. You'll need to also install diffutils.

Diffutils includes four utilities: diff, cmp, diff3 and sdiff. Diff
compares two files and shows the differences, line by line. The cmp
command shows the offset and line numbers where two files differ, or
cmp can show the characters that differ between the two files. The
diff3 command shows the differences between three files. Diff3 can be
used when two people have made independent changes to a common
original; diff3 can produce a merged file that contains both sets of
changes and warnings about conflicts. The sdiff command can be used
to merge two files interactively.

Install diffutils if you need to compare text files.

LAM (Local Area Multicomputer) is an Message-Passing Interface (MPI)
programming environment and development system for heterogeneous
computers on a network. With LAM/MPI, a dedicated cluster or an
existing network computing infrastructure can act as one parallel
computer to solve one problem. LAM/MPI is considered to be "cluster
friendly" because it offers daemon-based process startup/control as
well as fast client-to-client message passing protocols. LAM/MPI can
use TCP/IP and/or shared memory for message passing (different RPMs
are supplied for this -- see the main LAM website at
http://www.mpi.nd.edu/lam/ for details).<

LAM features a full implementation of MPI version 1 (with the
exception that LAM does not support cancelling of sends), and much of
version 2. Compliant applications are source code portable between LAM
and any other implementation of MPI. In addition to meeting the
standard, LAM/MPI offers extensive monitoring capabilities to support
debugging. Monitoring happens on two levels: On one level, LAM/MPI has
the hooks to allow a snapshot of a process and message status to be
taken at any time during an application run. The status includes all
aspects of synchronization plus datatype map/signature, communicator
group membership and message contents (see the XMPI application on the
main LAM website). On the second level, the MPI library can produce a
cumulative record of communication, which can be visualized either at
runtime or post-mortem.

microcode_ctl - updates the microcode on Intel x86/x86-64 CPU's

Mkinitrd creates filesystem images for use as initial ramdisk (initrd)
images. These ramdisk images are often used to preload the block
device modules (SCSI or RAID) needed to access the root filesystem.

In other words, generic kernels can be built without drivers for any
SCSI adapters which load the SCSI driver as a module. Since the
kernel needs to read those modules, but in this case it isn't able to
address the SCSI adapter, an initial ramdisk is used. The initial
ramdisk is loaded by the operating system loader (normally LILO) and
is available to the kernel as soon as the ramdisk is loaded. The
ramdisk image loads the proper SCSI adapter and allows the kernel to
mount the root filesystem. The mkinitrd program creates such a
ramdisk using information found in the /etc/modules.conf file.

mlocate is a locate/updatedb implementation. It keeps a database of
all existing files and allows you to lookup files by name.

The 'm' stands for "merging": updatedb reuses the existing database to avoid
rereading most of the file system, which makes updatedb faster and does not
trash the system caches as much as traditional locate implementations.

Install mod_perl if you're installing the Apache web server and you'd
like for it to directly incorporate a Perl interpreter.
