syntax: %(argv0)s [options] project ['Project Long Name']

Creates a new project with given name with everything running on a single
server.

Misc options:
   --verbose={0,1,2}    default: 1
   -v                   alias for --verbose=2
   --no_query           accept all directories without querying
   --user_name          default: $USER (%(USER)s)
   --delete_prev_inst   delete project-root first (from prev installation)
   --drop_db_first      drop database first (from prev installation)

Dir-options:
   --project_root       default: HOME/projects/PROJECT
   --key_dir            default: PROJECT_ROOT/keys
   --url_base           default: http://$NODENAME/ (http://%(NODENAME)s/)

   --html_user_url      default: URL_BASE/PROJECT/
   --html_ops_url       default: URL_BASE/PROJECT_ops/
   --cgi_url            default: URL_BASE/PROJECT_cgi/

Other:
   --db_name            default: PROJECT
   --db_user            default: USER_NAME
   --db_passwd          default: None
   --db_host            default: None

Example command line:
  ./make_project --project_root $HOME/boinc/projects --url_base http://boink/ yah 'YETI @ Home'

Then upload_dir = $HOME/boinc/projects/yah/upload
and  cgi_url    = http://boink/yah_cgi/

By default, directory options will be queried if they do not exist yet.

Steps to complete installation:

1. Set permissions for Apache:

   cat %(httpd_conf_template_filename)s >> /etc/apache/httpd.conf && apachectl restart

   (path to httpd.conf varies)

2. Add to crontab (as %(USER)s)
   (If cron cannot run "start", try using a helper script to set PATH and
   PYTHONPATH)

    0,5,10,15,20,25,30,35,40,45,50,55 * * * * %(proot)s/bin/start --cron

To start, show status, stop BOINC daemons run:

    %(proot)s/bin/start
    %(proot)s/bin/status
    %(proot)s/bin/stop

Master         URL: %(html_user_url)s
Administration URL: %(html_ops_url)s

3. Add Work Generator, Validator and Assimilator daemons for your applications


Further steps are necessary to add applications and work.
