What to do to make a public release

Take the latest internal release. Unpack it and go to its main directory.
Make sure that the script 'make_public_header' is executable from here.
Alter the second line above, such that the major and minor release
number are ok.
Run this script. This does the following:
    Remove the test directory.
    Remove developer_scripts dir
    Remove doc_tex dir
    Find all .C and .h files and collect them in a file
    Run the script 'make_public_header' to update the headers of all files.
    Edit include/CGAL/config.h
	#define CGAL_VERSION ...
	#define CGAL_VERSION_NR ...

The rest is done manually still.
Add README file.
Rename the current directory to CGAL-x.y.
Do
  find CGAL-x.y -exec touch 01221530 {} \;
in order to touch all files (Here the date/time  Jan 22, 15:30 was used
as an example)
Make CGAL-x.y.tar.gz with tar and gzip and CGAL-x.y.zip with zip.

The documentation goes separately from the rest, except for the installation
manual.
