The file will be called @file{gt-@var{path}.h} where @var{path} is the
pathname relative to the @file{gcc} directory with slashes replaced by
@verb{|-|}, so for example the header file to be included in
-@file{cp/parser.c} is called @file{gt-cp-parser.c}. The
+@file{cp/parser.c} is called @file{gt-cp-parser.h}. The
generated header file should be included after everything else in the
source file. Don't forget to mention this file as a dependency in the
@file{Makefile}!
