having installed rEFIt-0.14.dmg on Mac OS X Lion (10.7.2) there is an undocumented default timeout of 20 seconds without any timeout specification in refit.conf. In contrast to the description in refit.conf setting the timeout to 0 DOES NOT disable automatic booting (i.e., no timeout). However, this can be archieved through "timeout -1". There is no maximum value for timeout given and no type/format (e.g. integer) mentioned.
