+@subsection How to save breakpoints to a file
+
+To save breakpoint definitions to a file use the @w{@code{save
+breakpoints}} command.
+
+@table @code
+@kindex save breakpoints
+@cindex save breakpoints to a file for future sessions
+@item save breakpoints [@var{filename}]
+This command saves all current breakpoint definitions together with
+their commands and ignore counts, into a file @file{@var{filename}}
+suitable for use in a later debugging session.  This includes all
+types of breakpoints (breakpoints, watchpoints, catchpoints,
+tracepoints).  To read the saved breakpoint definitions, use the
+@code{source} command (@pxref{Command Files}).  Note that watchpoints
+with expressions involving local variables may fail to be recreated
+because it may not be possible to access the context where the
+watchpoint is valid anymore.  Because the saved breakpoint definitions
+are simply a sequence of @value{GDBN} commands that recreate the
+breakpoints, you can edit the file in your favorite editing program,
+and remove the breakpoint definitions you're not interested in, or
+that can no longer be recreated.
