customize and/or edit carrington admin settings page

[jkd77]

Using Carrington Jam there's really only 3 options in the admin
settings page but I'd like to be able to hide some of these if they're
no longer connected to anything, notably the 'About Text'. I found the
code responsible located in carrington-core/admin.php but I'd rather
not edit anything in this directory for fear of future compatibility
issues. Is there a way I can overload the functions in carrington-core/
admin.php? I guess in general I'm curious how to begin editing and
creating my own admin settings area via carrington.

Any help would be greatly appreciated!
