\begin{itemize}
- \item prelinking reduces the time needed to start an executable
- \item it is extensively used on android
- \item it has to be configured to know which libraries needs to be
- prelinked and will assign a fixed address for each available
- symbol thus removing the need to relocate symbols when starting
- an executable.
- \item be careful of security implications!
