-You can also instruct @value{GDBN} to skip all functions in a file, with,

+Functions may be skipped by providing either a function name, linespec

+
+On Posix systems the form of the regular expression is
+``Extended Regular Expressions''.  See for example @samp{man 7 regex}
+on @sc{gnu}/Linux systems.  On non-Posix systems the form of the regular

+@item -rfunction @var{regexp}
+@itemx -rfu @var{regexp}
+Functions whose name matches @var{regexp} will be skipped over when

+This form is useful for complex function names.
+For example, there is generally no need to step into C++ std::string
+constructors or destructors.  Plus with C++ templates it can be hard to
