+This is paxctl for controlling PaX flags on a per binary basis. PaX
+is an intrusion prevention system that provides the best protection
+mechanisms against memory corruption bugs. Some applications are not
+compatible with certain features (due to design or bad engineering)
+and therefore they have to be exempted from certain enforcements. It
+is also possible to use PaX in soft mode where none of the protection
+mechanisms are active by default - here paxctl can be used to turn
+them on for selected programs (e.g., network daemons, programs that
+process network data such as mail clients, web browsers, etc).
+
+PaX is provided by a separate kernel patch, that you need to install 
+manually. You can get it from: https://grsecurity.net/

+# 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.
