+Prelink is a program that modifies ELF shared libraries and ELF dynamically
+linked binaries in such a way that the time needed for the dynamic linker to
+perform relocations at startup significantly decreases. Due to fewer
+relocations, the run-time memory consumption decreases as well (especially
+the number of unshareable pages). The prelinking information is only used
+at startup time if none of the dependent libraries have changed since
+prelinking; otherwise, programs are relocated normally.
+
+There is a script in the prelink documentation directory that is suitable
+for a cron job. Before setting up a cron job, first run prelink on the
+system and then read the script and modify it as needed.
+
+This requires libelf.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
