@ -845,14 +845,8 @@ SYNOPSIS
asection *bfd_get_section_by_name (bfd *abfd, const char *name);
DESCRIPTION
Run through @var{abfd} and return the one of the
<<asection>>s whose name matches @var{name}, otherwise <<NULL>>.
@xref{Sections}, for more information.
This should only be used in special cases; the normal way to process
all sections of a given name is to use <<bfd_map_over_sections>> and
<<strcmp>> on the name (or better yet, base it on the section flags
or something else) for each section.
Return the most recently created section attached to @var{abfd}
named @var{name}. Return NULL if no such section exists.
