Usage: ${0:t} [--cgi] [--app] /LOCATION

${0:t} is a command to generate Apache's .htaccess for you.
Please specify location (local part of URL) for current directory.

If --cgi option is given, this will also copy cgi-bin/runyatt.cgi for you.
If --app option is given, ../app.psgi is also copied.

Typically, if your DOCUMENT_ROOT is /var/www/html and
your contents are placed under /var/www/html/foo/bar,
location will be /foo/bar.
