syntax: %(argv0)s [options] project-dir-name 'Project Long Name' app-exe 'AppName'

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:
   --base               default: $HOME (%(HOME)s)
   --key_dir            default: BASE/keys
   --project_root       default: BASE/projects/PROJECT
   --url_base           REQUIRED; e.g.: http://maggie.ssl.berkeley.edu/

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

Example command line:
  ./make_project --base $HOME/boinc --url_base http://boink/ yah 'YETI @ Home' \\
                  upper_case 'UpperCase'

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.
