Subject: Configuration examples for new AliGenParam added. param4 does not work for the moment
X-Git-Url: http://git.uio.no/git/?p=u%2Fmrichter%2FAliRoot.git;a=commitdiff_plain;h=395b2e02a06ffd184a83089aa85d18673b008e2a;ds=sidebyside

Configuration examples for new AliGenParam added. param4 does not work for the moment
because of a tempory problem of CINT with pointers to functions.
