 * log into issues.roundup-tracker.org
 * get a working copy of roundup/website/issues from the SCM, either via
   hg clone http://roundup.hg.sourceforge.net:8000/hgroot/roundup/roundup
   or download a snapshot:
   http://roundup.hg.sourceforge.net/hgweb/roundup/roundup/archive/default.tar.gz
 * copy the files into the tracker instance, using sudo:
      sudo -u roundup cp <file> /home/roundup/trackers/roundup/...
 * restart the roundup server:
      sudo -u roundup /etc/init.d/roundup restart

www.roundup-tracker.org:

 * log into sf.net
      ssh -t <user>,roundup@shell.sourceforge.net create
 * set project_home:
      project_home=/home/project-web/roundup
 * activate the virtualenv
      cd ${project_home}
      . docbuilder/bin/activate
 * update the working copy
      cd ${project_home}/src/roundup/website/www
      hg pull -u /home/scm_hg/r/ro/roundup/roundup
   (The warning about "Not trusting file 
   /home/scm_hg/r/ro/roundup/roundup/.hg/hgrc from untrusted user" 
   can be ignored)
 * build it
      make html
 * you may also "make clean"
 * install it
      cp -r ./html/* ${project_home}/htdocs/

(I think I can simplify the Makefile above such that the installation will be included as a make target.)
