-@section Targets
-Each port of BFD to a different machine requries the creation of a
-target back end. All the back end provides to the root part of BFD is
-a structure containing pointers to functions which perform certain low
-level operations on files. BFD translates the applications's requests
-through a pointer into calls to the back end routines.
-
-When a file is opened with @code{bfd_openr}, its format and target are
-unknown. BFD uses various mechanisms to determine how to interpret the
-file. The operations performed are:
-@itemize @bullet
-@item
-First a BFD is created by calling the internal routine
-@code{new_bfd}, then @code{bfd_find_target} is called with the target
-string supplied to @code{bfd_openr} and the new BFD pointer.
-@item
-If a null target string was provided to
-@code{bfd_find_target}, it looks up the environment variable
-@code{GNUTARGET} and uses that as the target string.
-@item
-If the target string is still NULL, or the target string
-is @code{default}, then the first item in the target vector is used as
-the target type. @xref{bfd_target}.
-@item
-Otherwise, the elements in the target vector are
-inspected one by one, until a match on target name is found. When
-found, that is used.
-@item
-Otherwise the error @code{invalid_target} is returned to
-@code{bfd_openr}.
-@item
-@code{bfd_openr} attempts to open the file using
-@code{bfd_open_file}, and returns the BFD.
-@end itemize
-Once the BFD has been opened and the target selected, the file format
-may be determined. This is done by calling @code{bfd_check_format} on
-the BFD with a suggested format. The routine returns @code{true} when
-the application guesses right.

+DESCRIPTION
+ Each port of BFD to a different machine requries the creation
+ of a target back end. All the back end provides to the root
+ part of BFD is a structure containing pointers to functions
+ which perform certain low level operations on files. BFD
+ translates the applications's requests through a pointer into
+ calls to the back end routines.
+
+ When a file is opened with <<bfd_openr>>, its format and
+ target are unknown. BFD uses various mechanisms to determine
+ how to interpret the file. The operations performed are:
+
+ o Create a BFD by calling the internal routine
+ <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
+ target string supplied to <<bfd_openr>> and the new BFD pointer.
+
+ o If a null target string was provided to <<bfd_find_target>>,
+ look up the environment variable <<GNUTARGET>> and use
+ that as the target string.
+
+ o If the target string is still <<NULL>>, or the target string is
+ <<default>>, then use the first item in the target vector
+ as the target type, and set <<target_defaulted>> in the BFD to
+ cause <<bfd_check_format>> to loop through all the targets.
+ @xref{bfd_target}. @xref{Formats}.
+
+ o Otherwise, inspect the elements in the target vector
+ one by one, until a match on target name is found. When found,
+ use it.
+
+ o Otherwise return the error <<bfd_error_invalid_target>> to
+ <<bfd_openr>>.
+
+ o <<bfd_openr>> attempts to open the file using
+ <<bfd_open_file>>, and returns the BFD.
+
+ Once the BFD has been opened and the target selected, the file
+ format may be determined. This is done by calling
+ <<bfd_check_format>> on the BFD with a suggested format.
+ If <<target_defaulted>> has been set, each possible target
+ type is tried to see if it recognizes the specified format.
+ <<bfd_check_format>> returns <<true>> when the caller guesses right.
