+.Sh NAME
+.Nm elf_hash
+.Nd compute a hash value for a string
+.Sh LIBRARY
+.Lb libelf
+.Sh SYNOPSIS
+.In libelf.h
+.Ft "unsigned long"
+.Fn elf_hash "const char *name"
+.Sh DESCRIPTION
+Function
+.Fn elf_hash
+computes a portable hash value for the null terminated string
+pointed to by argument
+.Ar name .
+.Pp
+The hash value returned is will be identical across
+machines of different architectures.
+This allows hash tables to be built on one machine and
+correctly used on another of a different architecture.
+The hash value returned is also guaranteed
+.Em not
+to be the bit pattern of all ones (~0UL).
+.Sh IMPLEMENTATION NOTES
+The library internally uses unsigned 32 bit arithmetic to compute
+the hash value.
