+0000: Introduction
+----------------------------------------------------------------------
+
+Libguestfs is a fairly low-level C library for accessing disk images.
+To perform everyday operations we've written "virt tools" over this.
+
+Virt tools use libguestfs, qemu, qemu-img and many other programs and
+perform operations that would hard to do by hand.
+
+In the case of virt-resize, the tool does calculations (like partition
+sizing) that require hard work and experience, so the virt-resize tool
+captures a lot of knowledge about how not to break Windows bootloaders
+and how to align partitions for performance that would be hard to
+teach.
