+ZFS is a modern filesystem originally developed for SOLARIS.
+It provides many functionalities such as snapshots, data compression,
+data recovery and many more.
+
+For more information about ZFS on linux, visit http://zfsonlinux.org
+
+You'll need the kernel source code to be able to compile this.
+This package is kernel dependent, so you'll need to recompile it
+for every new kernel you choose to run.
+
+If you don't have a /usr/src/linux symlink pointing to your real
+kernel directory (the script looks for it there by default), specify
+your kernel source destination by
+
+  LINUXPATH=<path to your kernel source> ./zfs-on-linux.SlackBuild
+
+NOTE: you better run this on x86_64 systems.

+# 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.
