=item SUBMIT_LABEL (default: Sign In)

the label for the submit button

=item COMMENT (default: Please enter your username and password in the fields below.)

a message provided on the first login attempt

=item REMEMBERUSER_OPTION (default: 1)

provide a checkbox to offer to remember the users name in a cookie so that
their user name will be pre-filled the next time they log in

=item REMEMBERUSER_LABEL (default: Remember User Name)

the label for the remember user name checkbox

=item REMEMBERUSER_COOKIENAME (default: CAPAUTHTOKEN)

the name of the cookie where the user name will be saved

=item REGISTER_URL (default: <none>)

the URL for the register new account link

=item REGISTER_LABEL (default: Register Now!)

the label for the register new account link

=item FORGOTPASSWORD_URL (default: <none>)

the URL for the forgot password link

=item FORGOTPASSWORD_LABEL (default: Forgot Password?)

the label for the forgot password link

=item INVALIDPASSWORD_MESSAGE (default: Invalid username or password<br />(login attempt %d)

a message given when a login failed

=item INCLUDE_STYLESHEET (default: 1)

use this to disable the built in style-sheet for the login box so you can provide your own custom styles

=item FORM_SUBMIT_METHOD (default: post)

use this to get the form to submit using 'get' instead of 'post'

=item FOCUS_FORM_ONLOAD (default: 1)

use this to automatically focus the login form when the page loads so a user can start typing right away.

=item BASE_COLOUR (default: #445588)

This is the base colour that will be used in the included login box.  All other
colours are automatically calculated based on this colour (unless you hardcode
the colour values).  In order to calculate other colours, you will need the
Color::Calc module.  If you do not have the Color::Calc module, then you will
need to use fixed values for all of the colour options.  All colour values
besides the BASE_COLOUR can be simple percentage values (including the % sign).
For example if you set the LIGHTER_COLOUR option to 80%, then the calculated
colour will be 80% lighter than the BASE_COLOUR.

=item LIGHT_COLOUR (default: 50% or #a2aac4)

A colour that is lighter than the base colour.

=item LIGHTER_COLOUR (default: 75% or #d0d5e1)

A colour that is another step lighter than the light colour.

=item DARK_COLOUR (default: 30% or #303c5f)

A colour that is darker than the base colour.

=item DARKER_COLOUR (default: 60% or #1b2236)

A colour that is another step darker than the dark colour.

=item GREY_COLOUR (default: #565656)

A grey colour that is calculated by desaturating the base colour.
