Updated the http://nmr-relax.com HTML user manual to version 1.3.13.

Modified the release checklist for large files!

The Mac OS X DMG file is ~120 Mb, so the uploading command for the distribution files has been
updated to show the progress.

Modified the http://nmr-relax.com download page to point to relax version 1.3.13.

The Mac OS X stand-alone application is now included.

Added the relax 1.3.13 version of the user manual to the repository.

Merged r14998 from the main 1.3 line as this is essential for the user manual compilation.

The command used was:
svn merge -r14997:14998 svn+ssh://bugman@.../svn/relax/1.3

Bug fix for the compilation of the user manual.

The molecule user function class used the temporary variable i, which was causing the
fetch_docstrings script to fail.

Changed the version in the version file to 1.3.13.

Merged the CHANGES file for relax version 1.3.13 back into the main 1.3 line.

The command used was:

Updated the CHANGES file for relax 1.3.13.

relax version 1.3.13.

This release introduces the second version of the relax GUI. This is a major rewrite of the entire
GUI code base. The GUI should now be much more flexible, being able to handle all the different
ways NMR data is collected and errors are measured. It now has the full flexibility of the prompt/
scripting interface by the implementation of GUI versions of the user functions and now supports
small organic molecules, RNA, DNA, sugars, etc. This flexibility will allow all other analysis
types (reduced spectral density mapping, N-state model, the frame order theory, consistency testing,
etc.) to be added to the GUI in the future. The GUI is now fully tested and fully functional and
bug free on all major platforms including GNU/Linux, Mac OS X and MS Windows.

In addition, there are improvements to the frame order theory. And significant bug fixes throughout
the program.
