+pledge is a port of OpenBSD's syscall to Linux by Justine Tunney.
+This script builds a shared library (used to be injected via LD_PRELOAD)
+and a command line utility to restrict program exection privileges and
+limit parameters as maximum niceness, cpu time, virtual memory, file
+descriptors, child proccess and individual file sizes.
+
+NOTE:
+* pledge help is available via the -h option
+* to run pledge at glibc executable load time:
+  strace -vff bash -c \
+    '_PLEDGE=4194303,0 LD_PRELOAD=/usr/lib64/pledge/sandbox.so ls'

+# 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.
