== build Checking out a relax branch == If you would like to play with relax branch rather than the main [[http://www.nmr-relax.com/download.html relax downloads]], the [[http://subversion.tigris.org/ Subversion]] program should first be installed. First the relax sources can be checked out of the source code repository and the C modules compiled:
<source lang="bash">
svn co svn://svn.gna.org/svn/relax/branches/relax_disp relax_disp
scons
# Optional building of the user manual, if a LaTeX installation is available.
scons user_manual_pdf
</source>
If the svn command does not work, try:
<source lang="bash">
svn co http://svn.gna.org/svn/relax/branches/relax_disp relax_disp
</source>
