    (description
     "Pam-krb5 is a Kerberos PAM module for either MIT Kerberos or Heimdal.
It supports ticket refreshing by screen savers, configurable
authorization handling, authentication of non-local accounts for network
services, password changing, and password expiration, as well as all the
standard expected PAM features.  It works correctly with OpenSSH, even
with @code{ChallengeResponseAuthentication} and @code{PrivilegeSeparation}
enabled, and supports extensive configuration either by PAM options or in
krb5.conf or both.  PKINIT is supported with recent versions of both MIT
Kerberos and Heimdal and FAST is supported with recent MIT Kerberos.")

In indent mode, your script is reformatted with standard spacing.

In tokenize mode, you can see the elements of every command you use.

In HTMLize mode, your script is converted to a beautiful colored HTML file,

With sedsed you can master any sed script.  No more secrets, no more hidden

     "hungrycat prints the contents of a file to standard output, while
simultaneously freeing the disk space it occupied.  It is useful if you need
to process a large file, don't have enough space to store both the input and
output files, and don't need the input file afterwards.
While similar in principle to running @command{cat} immediately followed by
@command{rm}, @command{hungrycat} actually frees blocks as soon as they are
printed instead of after the entire file has been read, which is often too
late.")

    (description "@command{ngrep} is like GNU grep applied to the network
layer.  It's a PCAP-based tool that allows you to specify an extended regular
or hexadecimal expression to match against data payloads of packets.  It
understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6,
IGMP and Raw, across a wide variety of interface types, and understands BPF
filter logic in the same fashion as more common packet sniffing tools, such as
tcpdump and snoop.")
