cups-base has several options:

 [X] GNUTLS    Build with GNUTLS library
 [ ] PHP       Build PHP support
 [ ] PYTHON    Build PYTHON support
 [ ] LIBPAPER  Build with libpaper support
 [ ] DNSSD     Build with DNS_SD (avahi) support
 [ ] PAM       Build with PAM support
 [ ] LDAP      Build with LDAP support
 [ ] DBUS      Build with DBUS support

Where can I find documentation regarding these options, so I can determine 
which ones I need?
