===Updating your L<sup>A</sup>TEX install===
Once the class files are successfully downloaded, you will need to run '''texhash'''  or '''texconfig rehash'''  to update L<sup>A</sup>TEX about the new class files.  For reference, a successful run of '''texhash'''  produces the following output:
<pre>
jgodwin&#36; texhash
texhash: Updating /usr/local/texlive/2010/../texmf-local/ls-R... 
texhash: Updating /usr/local/texlive/2010/texmf/ls-R... 
texhash: Updating /usr/local/texlive/2010/texmf-config/ls-R... 
texhash: Updating /usr/local/texlive/2010/texmf-dist/ls-R... 
texhash: Updating /usr/local/texlive/2010/texmf-var/ls-R... 
texhash: Done.
</pre>
To determine if these files are found successfully, go into &#36;RSFROOT/book/rsf/manual and run '''scons manual.read''' .  If L<sup>A</sup>TEX complains about being unable to find the class files then you should re-run texhash, or make sure that your class files are in the proper location.  If you are still having difficulties, then contact the [[SEGTeX|SEGTeX webpage]] or the user mailing list for further information.
