+    (description
+     "Squashfs is a highly compressed read-only file system for Linux.  It
+compresses files, inodes, and directories with one of several compressors.
+All blocks are packed to minimize the data overhead, and block sizes of
+between 4K and 1M are supported.  It is intended to be used for archival use,
+for live media, and for embedded systems where low overhead is needed.
+
+The squashfs-tools-ng package offers alternative tooling to create and extract
+such file systems.  It is not based on the older squashfs-tools package and
+its tools have different names:
+
+@enumerate
+@item @command{gensquashfs} produces SquashFS images from a directory or
+@command{gen_init_cpio}-like file listings and can generate SELinux labels.
+@item @command{rdsquashfs} inspects and unpacks SquashFS images.
+@item @command{sqfs2tar} and @command{tar2sqfs} convert between SquashFS and
+tarballs.
+@item @command{sqfsdiff} compares the contents of two SquashFS images.
+@end enumerate
+
+These commands are largely command-line wrappers around the included
+@code{libsquashfs} library that intends to make SquashFS available to other
+applications as an embeddable, extensible archive format.
+
+Both the library and tools operate deterministically: same input will produce
+byte-for-byte identical output.")
+    ;; Upstream goes to some lengths to ensure that libsquashfs is LGPL3+.
