I update the paragraph for this command a little bit,

@kindex maint print c-tdesc @r{[}@var{file}@r{]}
@item maint print c-tdesc
Print the target description (@pxref{Target Descriptions}) as
a C source file.  By default, the target description is for the current
target, but if the optional argument @var{file} is provided, that file
is used to produce the description.  The @var{file} should be an XML
document, of the form described in @ref{Target Description Format}.
The created source file is built into @value{GDBN} when @value{GDBN} is
built again.  This command is used by developers after they add or
modify XML target descriptions.

but GDB users are not GDB developers.  Why does user manual documents
some commands users never use?  IMO, these documents should be
documented in GDB internals.
