Most of these files were obtained (as of 2001-12-09) from
http://www.pa.msu.edu/ftp/pub/unix/cd1.3.tar.gz

This software was written originally by G. Edward Johnson at NIST, but it is
no longer maintained by him.  It is public-domain software except for the
small part licensed under the libgd license (see his documentation).

The PLplot developer's contribution is CMakeLists.txt, cddll.h, and some
small visibility modifications to cd.h.  We call the resulting library,
libnistcd to distinguish it from all the other "libcd" libraries out there.

Welcome, and thanks for downloading CGM Draw, a package for creating
CGM files from a "C" program.  If you are reading this then you probably
have already unpacked the distribution.  You can make it by typing
"make all"  this will make libcd.a  the cd library, as well as several
example programs (cdsimple, cdtest, color16, cdexpert, cdmulti, cdtext.)
Please read over the documentation in cd.html before using the package.

Every effort has been made to ensure that the generated cgm files
conform to the standard, however, if you do not use the library
properly, you could generate invalid metafiles that no one is able
to read, so be careful.

Documentation for cd is included with the package, and is available from
http://speckle.ncsl.nist.gov/~lorax/cgm/cd.html
General information about CGM is available many places on the web, including
http://speckle.ncsl.nist.gov/~lsr/cgm.htm
This distribution may be retrieved via ftp from
zing.ncsl.nist.gov in the directory "cgm"  it will have the
name cd followed by the version number.

I have tested CGM Draw on SunOs4, Solaris2, Ultrix, Linux, and IRIX.
I have heard from other people it works under OpenVMS and Dos. It
should compile and run on just about any Unix system, and probably
other systems as well.

I have switched jobs (within NIST) so there will be no further enhancements
of this package.  If any bugs come up, I will try to fix them.
