+    (description "Dwarves is a set of tools that use the debugging information
+inserted in ELF binaries by compilers such as GCC, used by well known
+debuggers such as GDB.
+
+Utilities in the Dwarves suite include @command{pahole}, that can be used to
+find alignment holes in structures and classes in languages such as C, C++,
+but not limited to these.  These tools can also be used to encode and read the
+BTF type information format used with the kernel Linux @code{bpf} syscall.
+
+The @command{codiff} command can be used to compare the effects changes in
+source code generate on the resulting binaries.
+
+The @command{pfunct} command can be used to find all sorts of information
+about functions, inlines, decisions made by the compiler about inlining, etc.
+
+The @command{pahole} command can be used to use all this type information to
+pretty print raw data according to command line directions.
+
+Headers can have its data format described from debugging info and offsets from
+it can be used to further format a number of records.
+
+Finally, the @command{btfdiff} command can be used to compare the output of
+pahole from BTF and DWARF, to make sure they produce the same results. ")
