+Sysdig is open source, system-level exploration: capture system state and
+activity from a running Linux instance, then save, filter and analyze. Sysdig is
+scriptable in Lua and includes a command line interface and a powerful
+interactive UI, csysdig, that runs in your terminal. Think of sysdig as strace +
+tcpdump + htop + iftop + lsof + awesome sauce. With state of the art container
+visibility on top.
+
+To build the package for a kernel different from the running one, start the
+script setting the KERNEL variable as in
+KERNEL=2.6.38.8 ./sysdig.SlackBuild

+# 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.
