Used \newcommand to abstract the four actor names in di-git-ally managing love letters presentation:

\newcommand{\oneactor}{pretty-zinta}
\newcommand{\twoactor}{raaani-mukerji}
\newcommand{\threeactor}{nayantaaara}
\newcommand{\fouractor}{aishvarya-ray}

You can now get the sources from gitorious, and replace the above names to your liking, and rebuild the presentation by invoking make from the sources directory.

$ git clone git://gitorious.org/di-git-ally-managing-love-letters/mainline.git
