+These are the userspace tools required for bcache.
+
+Bcache is a patch for the Linux kernel to use SSDs to cache other block
+devices. For more information, see http://bcache.evilpiepirate.org.
+Documentation for the run time interface is included in the kernel tree, in
+Documentation/bcache.txt.
+
+Included:
+
+make-bcache
+Formats a block device for use with bcache. A device can be formatted for use
+as a cache or as a backing device (requires yet to be implemented kernel
+support). The most important option is for specifying the bucket size.
+Allocation is done in terms of buckets, and cache hits are counted per bucket;
+thus a smaller bucket size will give better cache utilization, but poorer write
+performance. The bucket size is intended to be equal to the size of your SSD's
+erase blocks, which seems to be 128k-512k for most SSDs; feel free to
+experiment.
+
+bcache-super-show
+Prints the bcache superblock of a cache device or a backing device.
+
+Udev rules
+The first half of the rules do auto-assembly and add uuid symlinks
+to cache and backing devices.  If util-linux's libblkid is
+sufficiently recent (2.24) the rules will take advantage of
+the fact that bcache has already been detected.  Otherwise
+they call a small probe-bcache program that imitates blkid.
+
+The second half of the rules add symlinks to cached devices,
+which are the devices created by the bcache kernel module.
+
+Initramfs support
+Currently initramfs-tools, mkinitcpio and dracut are supported.

+# 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.
