The MECCA 2000 software depends on, or makes use of, the following third
party software programs and/or components.  Amgraf, Inc. hereby
acknowledges their contributors.

Please note that all of them are available as ready-built packages from
FreeBSD (see below), or their source code can be downloaded by customers
to build the package.  Thusly none of them is included in the MECCA 2000
distribution set.

FreeBSD
=======
The (high performance, highly stable) operating system software.  Please
visit http://www.freebsd.org/ to find out more on what they provide for
you.

XFree86
=======
The MECCA 2000 software product includes software developed by The XFree86
Project, Inc (http://www.xfree86.org/) and its contributors.

XFree86 is, in a nutshell, the X Window System for PC (x86 architecture).
For more information about XFree86 and the XFree86 Project, please visit
URL noted above.  For information about the X Window System, the GUI system
born out of the MIT Athena Project, please visit http://www.x.org/.

Tcl/Tk
======
A scripting language that can easily be embedded into an application, Tcl/Tk
was the creation of Professor John Ousterhout, who contributed it to the
public use.  It is now an Open Source project, hosted at Sourceforge
(http://www.sourceforge.net/projects/tcl).  More information about Tcl/Tk
can also be found at http://www.tcl.tk/.

NetPBM
======
A collection of bitmap file format conversion and processing filters, is
now also an Open Source project hosted at Sourceforge
(http://www.sourceforge.net/projects/netpbm).

MECCA 2000 makes use of this package in two areas:

  1. Its drawing window content dump -- written to PNM format only.
  2. Importing bitmap files in these formats: TIFF, PNM, PNG.

As of this writing, none of these operations involves the use of any
GPL-covered components in NetPBM.  To find out what is GPL (GNU General
Public License), please visit http://www.gnu.org/, follow the Licenses
link there.  For your convenience, FreeBSD hosts a page containing its
Copyright along with GPL and some others, at
http://www.freebsd.org/copyright/index.html.

Libpng
======
PNG (Portable Network Graphics) format bitmap file processing library
routines.  When a colored bitmap image must preserve transpareny, PNG
is the only format supported by MECCA 2000.
Please visit http://www.libpng.org/ for more information about PNG.

JPEG
====
From IJG (Independent JPEG Group), a library of JPEG file reader/writer
routines, plus applications to create/decompress JPEG format files.  More
can be found at http://www.ijg.org/, or http://www.jpeg.org/.

Ispell
======
The fast spelling checker currently maintained by Dr. Geoff Kuenning (PhD).
It supports many different languages, and is run whenever the MECCA 2000 user
conducts spelling-check.  Dr. Kuenning runs a website for International Ispell,
where detailed information on how to customize it can be found, along with the
software source code, plus alternative dictionaries download, at:
http://fmg-www.cs.ucla.edu/geoff/ispell.html.

T1utils
=======
Type 1 Utilities -- six free UNIX/Windows command-line tools for dealing with
Type 1 fonts.  It is a revision of I. Lee Hetherington's beloved t1utils
package.  Now maintained by Eddie Kohler, who runs a website for it at
http://www.lcdf.org/~eddietwo/type/.

LCDF-TYPETOOLS
==============
Extra utilities written by the maintainer of t1utils (above), Assistant
Professor Eddie Kohler at UCLA (as of this writing).  Among the utilties is
CFFtoType1, which converts a CFF (Compact Font Format, used by Adobe in PDF
files, as well as in some OpenType fonts) to Type 1 so the font can be sent
to an older PostScript imager/printer.
http://www.lcdf.org/

Freetype 2 Library
==================
Font software engine that can deal with PostScript and TrueType fonts.
Currently at: http://freetype.sourceforge.net/

Potrace
=======
Fast B&W bitmap outline tracer.  http://potrace.sourceforge.net
