except that @file{$cdir} is not searched because the compilation directory
is not relevant to scripts.
+If @code{-s} is specified, then @value{GDBN} searches for @var{filename}
+on the search path even if @var{filename} specifies a directory.
+The search is done by appending @var{filename} to each element of the
+search path. So, for example, if @var{filename} is @file{mylib/myscript}
+and the search path contains @file{/home/user} then @value{GDBN} will
+look for the script @file{/home/user/mylib/myscript}.
+The search is also done if @var{filename} is an absolute path.
+For example, if @var{filename} is @file{/tmp/myscript} and
+the search path contains @file{/home/user} then @value{GDBN} will
+look for the script @file{/home/user/tmp/myscript}.
+For DOS-like systems, if @var{filename} contains a drive specification,
+it is stripped before concatenation. For example, if @var{filename} is
+@file{d:myscript} and the search path contains @file{c:/tmp} then @value{GDBN}
+will look for the script @file{c:/tmp/myscript}.
+
If @code{-v}, for verbose mode, is given then @value{GDBN} displays
each command as it is executed. The option must be given before
@var{filename}, and is interpreted as part of the filename anywhere else.

The Python list @code{gdb.pretty_printers} contains an array of
functions that have been registered via addition as a pretty-printer.
+Each @code{gdb.Progspace} contains a @code{pretty_printers} attribute.
Each @code{gdb.Objfile} also contains a @code{pretty_printers}
attribute.

+If no pretty-printer is found in the objfile lists, @value{GDBN} then

After these lists have been exhausted, it tries the global
@code{gdb.pretty-printers} list, again calling each function until an
object is returned.
Python code is read into @value{GDBN}, you may need to import the
@code{gdb} module explicitly.

+It consists of all of the objfiles of the program.

+This function returns the program space of the currently selected inferior.

+The @code{pretty_printers} attribute is a list of functions. It is
