seejpeg:  card being used.  To aid it, various hints may be given as program
seejpeg:  options.  In the worst case, it may be overridden.

noweb-2.8a: Noweb is a literate-programming tool like FunnelWEB or nuweb, only
noweb-2.8a: simpler.  A noweb file contains program source code interleaved with
noweb-2.8a: documentation.  When noweb is invoked, it writes the program source
noweb-2.8a: code to the output files mentioned in the noweb file, and it writes
noweb-2.8a: a TeX file for typeset documentation.  The author recommends using 
noweb-2.8a: LaTeX; noweb comes with an efficient LaTeX->HTML converter, so the
noweb-2.8a: resulting programs can easily be browsed on the World-Wide Web.
noweb-2.8a: More info can be found at URL http://www.cs.virginia.edu/~nr/noweb
noweb-2.8a: and on the USENET news group comp.programming.literate.

samba-1.9.17p2: Samba 1.9.17p2
samba-1.9.17p2:
samba-1.9.17p2: Samba is a Unix based SMB file server. This allows a Unix
samba-1.9.17p2: host to act as a file and print server for SMB clients. This
samba-1.9.17p2: includes Lan-Manager compatible clients such as LanManager 
samba-1.9.17p2: for DOS, Windows95, Windows NT, OS/2, Pathworks and many more.
samba-1.9.17p2: If you have any PCs running SMB clients, such as a PC running 
samba-1.9.17p2: Windows95, then you can mount file space or printers from a
samba-1.9.17p2: Linux host, so that directories, files and printers on the
samba-1.9.17p2: Linux host are available on the PC.
samba-1.9.17p2:

sample_users: sample users 'gonzo', 'snake', and 'satan'
sample_users:
sample_users: If you install this package, 3 sample users will be created 
sample_users: (gonzo, snake, satan). This package was once part of the AP disk
sample_users: series, but too many people installed it without noticing, and it
sample_users: was becoming the best known backdoor into Linux boxes all over the
sample_users: Internet (!). This package stems from a time before the "adduser"
sample_users: utility was put in Slackware, so it really isn't all that helpful
sample_users: anymore. You could use "adduser" to create some sample accounts
sample_users: nearly as easily

xgrabsc:  A screengrabber for X.
xgrabsc:
xgrabsc:  Xgrabsc and xgrab allow you do take PostScript shapshots of individual
xgrabsc:  X clients, regions of the X screen, or the entire screen.

emacspeak:         emacspeak  6.0
emacspeak:  
emacspeak:  Emacspeak is a speech output system that will allow
emacspeak:  someone who cannot see to work directly on a UNIX system.
emacspeak:  (Until now, the only option available to visually impaired
emacspeak:  users has been to use a talking PC as a terminal.)
emacspeak:  Emacspeak is built on top of Emacs.  Once you start emacs
emacspeak:  with emacspeak loaded, you get spoken feedback for
emacspeak:  everything you do.  Your mileage will vary depending on
emacspeak:  how well you can use Emacs.  There is nothing that you
emacspeak:  cannot do inside Emacs :-).  This package supports the
emacspeak:  DECtalk Express and DECtalk MultiVoice speech
emacspeak:  synthesizers.  For other synthesizers, look for separate
emacspeak:  driver packages.

emacspeak-dt:                emacspeak-dt 0.15
emacspeak-dt:  
emacspeak-dt:  Emacspeak by T. V. Raman enables blind users to use
emacspeak-dt:  emacs with a DECtalk speech synthesizer.  With this
emacspeak-dt:  driver, it can also be used with the DoubleTalk LT
emacspeak-dt:  synthesizer.
emacspeak-dt:  

lprng:    LPRng - An Extended Print Spooler System v.3.1.3.
lprng:
lprng:    The LPRng software is an enhanced, extended, and portable version of
lprng:    the Berkeley LPR software.  While providing the same general
lprng:    functionality, the implementation is completely new and provides
lprng:    support for the following features:  lightweight (no databases needed)lprng:    lpr, lpc, and lprm programs; dynamic redirection of print queues;
lprng:    automatic job holding; highly verbose diagnostics; multiple printers
lprng:    serving a single queue; client programs do not need to run SUID root;
lprng:    greatly enhanced security checks; and a greatly improved permission
lprng:    and authorization mechanism.
