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

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

Misc options:
   --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)
   --test_app           install example application
   --web_only           install web files, no executables (for Bossa, Bolt)
   --no_db              don't create the database
   --srcdir             where to find the source files (default: current directory)

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

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

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 https://tah.org/ tah 'Test@home'

Then upload_dir = $HOME/boinc/projects/tah/upload
and  cgi_url    = https://tah.org/tah_cgi/

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

   (path to httpd.conf varies; try /etc/httpd/ or /etc/apache2)

   Then restart the web server:

   /usr/sbin/apache2ctl restart
   (or /usr/sbin/apachectl restart)

-  Add to crontab (as %(USER)s)

    crontab -e

    and add the line:

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

-  Add a .htpasswd file in the project's html/ops directory:
    (You'll need this to access the project's Administrative page)

    htpasswd -c .htpasswd username

-  Add the project name and copyright holder for the boinc Web site:

    edit html/project/project.inc

    change PROJECT and COPYRIGHT_HOLDER
----------------------------

To start, show status, and stop the project, run:
