+ BFD keeps one atom in a BFD describing the
+ architecture of the data attached to the BFD: a pointer to a
+ <<bfd_arch_info_type>>.
+
+ Pointers to structures can be requested independently of a BFD
+ so that an architecture's information can be interrogated
+ without access to an open BFD.
+
+ The architecture information is provided by each architecture package.
+ The set of default architectures is selected by the macro
+ <<SELECT_ARCHITECTURES>>. This is normally set up in the
+ @file{config/@var{target}.mt} file of your choice. If the name is not
+ defined, then all the architectures supported are included.
+
+ When BFD starts up, all the architectures are called with an
+ initialize method. It is up to the architecture back end to
+ insert as many items into the list of architectures as it wants to;
+ generally this would be one for each machine and one for the
+ default case (an item with a machine field of 0).
+
+ BFD's idea of an architecture is implemented in @file{archures.c}.
