Zsh is a UNIX command interpreter (shell) which of the standard shells
most resembles the Korn shell (ksh), although it is not completely
compatible.  It includes enhancements of many types, notably in the
command-line editor, options for customising its behaviour, filename
globbing, features to make C-shell (csh) users feel more at home and
extra features drawn from tcsh (another `custom' shell).

If you want to use zsh completion system, you should type the following
commands:

	$ autoload -U compinstall
	$ compinstall

See also zshcompsys(1) manpage. :)

CVSup is a software package for distributing and updating collections
of files across a network.  It can efficiently and accurately mirror
all types of files, including sources, binaries, hard links, symbolic
links, and even device nodes.  CVSup's streaming communication
protocol and multithreaded architecture make it most likely the
fastest mirroring tool in existence today.  In addition to being
a great general-purpose mirroring tool, CVSup includes special
features and optimizations specifically tailored to CVS repositories.

This port of CVSup includes the GUI and requires X11.  For a version
that does not include the GUI, use the "net/cvsup-without-gui" port.

Vim is a virtually compatible, extremely enhanced, version of the UNIX
text editor vi.

There are a lot of enhancements above Vi: multi level undo, multi-windows
and buffers, syntax highlighting, command line editing, filename completion,
on-line help, visual selection, etc..  

Many features above standard vi's have been added:
    multiple windows and buffers, multi level undo, command line history,
    filename completion, selection highlighting, block operations (including
    column/rectangular blocks), syntax highlighting, on-line help, etc.
	Embeded Perl, Tcl, and Python support.
	See ":help vi_diff" for a summary of the differences between Vim and Vi.

	An X-windows aware or a full X-windows GUI version can also be built
	that allows full use of the mouse and pull-down menus

See http://www.vim.org/why.html for a full explanation of Vim's features.

Portability to all UNIX platforms, AmigaOS, Archimedes, Atari MiNT, BeOS,
M$-DOS, MacOS, OS/2, VMS, WinNT+Win95.

Nmap is a utility for network exploration and security auditing.
It supports various types of host discovery (determine which hosts
are up), many port scanning techniques for different protocols,
version detection (determine service protocols and application
versions listening behind ports), and TCP/IP stack fingerprinting
(remote host OS or device identification).  Nmap also offers
flexible target and port specification, decoy/stealth scanning,
sunRPC scanning, and much more.

Also included is Ncat, the nc(1) work-a-like of the Nmap project.
Refer to the separate port security/zenmap for those parts of the
Nmap toolset which depend on python.  The translated manual pages
for Nmap are contained in security/nmap-i18n-man.

TrafShow continuously displays the information regarding packet
traffic on the configured network interface that matches the boolean
expression. It periodically sorts and updates this information. It
may be useful for locating suspicious network traffic on the net.
