All of the IGES files on this CDROM have been compressed using GNU's
gZip. The DOS version of gZip has been included in the "software/dos"
directory. The file is a self-extracting PKZip archive. Please install
the gZip application and review its documentation. If you already have
a software package capable of handling gZipped files, you will not need
to install gZip.

IMPORTANT!!!! - The files on this CDROM have UNIX End-Of-Line
characters.  It is VERY IMPORTANT to use the "-a" parameter with gZip
when decompressing the files. This will perform an End-Of-Line
conversion, making the files DOS compatible. The resulting decompressed
file will be missing the ".igs" extension. This extension will need to
be added for most CAD packages to recognize the files.

Please consult the gZip documentation for all questions concerning
gZip.

Example:

gzip -dac d:\models\pcb\example\example.gz > c:\temp\example.igs

INSTALLING GZIP
---------------

To install gZip onto your system follow these steps.

From the DOS prompt:

1) Make a directory called "gzip" on your main hard drive,
   and go to that directory.
    Commands:  ---------
	md c:\gzip c:  cd \gzip


2) Execute the "gZip.exe" command from the CD-ROM. This will
   place all of the necessary files into the "gzip" directory
   previously created.
    Commands:  ---------
	(Assuming that your CD-ROM drive is letter "D")
	d:\software\dos\gzip124.exe

3) Modify the "c:\autoexec.bat" file. Add the "c:\gzip" directory
   to the "PATH" statement.
    Commands:  ---------
	edit c:\autoexec.bat

    Example Changes:  ----------------
	(Original line:) PATH=c:\dos;c:\util;c:\windows; (change to:)
	PATH=c:\dos;c:\util;c:\windows;c:\gzip;

4) Execute the "c:\autoexec.bat" to make DOS reload the PATH
   command.
    Commands:  ---------
	c:\autoexec.bat

-----

To test that gZip is now properly setup, from the c:\ directory try to
execute the command "gzip -h".

    Commands:  ---------
	c:  cd \ gzip -h

If gzip is properly installed you will see a brief explanation of all
of gzip's parameters.
