This file is part of BFD, the Binary File Descriptor library.
The function <<bfd_hash_table_init>> take as an argument a
function to use to create new entries. For a basic hash
table, use the function <<bfd_hash_newfunc>>. @xref{Deriving
- a New Hash Table Type} for why you would want to use a
+ a New Hash Table Type}, for why you would want to use a
different value for this argument.

Write other derived routines
You will want to write other routines for your new hash table,
- as well.

You will want an initialization routine which calls the
