-This is GDB, the GNU source-level debugger, presently running under un*x.
-
-Before compiling GDB, you must tell GDB what kind of machine you are
-running on.  To do this, type `config.gdb machine', where machine is
-something like `vax' or `sun2'.  For a list of valid machine types,
-type `config.gdb'.
-
-Normally config.gdb edits the makefile as necessary.  If you have to
-edit the makefile on a standard machine listed in config.gdb this
-should be considered a bug and reported as such.
-
-Once these files are set up, just `make' will do everything,
-producing an executable `gdb' in this directory.
-
-If you want a new (current to this release) version of the manual, you
-will have to use the gdb.texinfo file provided with this distribution.
-The gdb.texinfo file requires the texinfo-format-buffer command from
-emacs 18.55 or later.
-
-About languages other than C...
-
-C++ support has been integrated into gdb.  GDB should work with
-FORTRAN programs (if you have problem, please send a bug report), but
-I am not aware of anyone who is working on getting it to use the
-syntax of any language other than C or C++.  Pascal programs which use
-sets, subranges, file variables, or nested functions will not
-currently work.
-
-About -gg format...
-
-Currently GDB version 3.x does *not* support GCC's -gg format.  This
-is because it (in theory) has fast enough startup on dbx debugging
-format object files that -gg format is unnecessary (and hence
-undesirable, since it wastes space and processing power in gcc).  I
-would like to hear people's opinions on the amount of time currently
-spent in startup; is it fast enough?
-
-About remote debugging...
-
-The two files remote-multi.shar and remote-sa.m68k.shar contain two
-examples of a remote stub to be used with remote.c.  The the -multi
-file is a general stub that can probably be running on various
-different flavors of unix to allow debugging over a serial line from
-one machine to another.  The remote-sa.m68k.shar is designed to run
-standalone on a 68k type cpu and communicate properley with the
-remote.c stub over a serial line.
-
-About reporting bugs...
-
-The correct address for reporting bugs found with gdb is
-"bug-gdb@prep.ai.mit.edu".  Please send all bugs to that address.
-
-About xgdb...
-
-xgdb.c was provided to us by the user community; it is not an integral
-part of the gdb distribution.  The problem of providing visual
-debugging support on top of gdb is peripheral to the GNU project and
-(at least right now) we can't afford to put time into it.  So while we
-will be happy to incorporate user fixes to xgdb.c, we do not guarantee
-that it will work and we will not fix bugs reported in it.  Someone is
-working on writing a new XGDB, so improving (e.g. by fixing it so that
-it will work, if it doesn't currently) the current one is not worth it.
-
-For those intersted in auto display of source and the availability of
-an editor while debugging I suggest trying gdb-mode in gnu-emacs.
-Comments on this mode are welcome.
-
-About the machine-dependent files...
-
-m-<machine>.h (param.h is a link to this file).
-This file contains macro definitions that express information
-about the machine's registers, stack frame format and instructions.
-
-<machine>-opcode.h (opcode.h is a link to this file).
-<machine>-pinsn.c (pinsn.c is a link to this file).
-These files contain the information necessary to print instructions
-for your cpu type.
-
-<machine>-dep.c (dep.c is a link to this file).
-Those routines which provide a low level interface to ptrace and which
-tend to be machine-dependent.  (The machine-independent routines are in
-`infrun.c' and `inflow.c')
-
-About writing code for GDB...
-
-We appreciate having users contribute code that is of general use, but
-for it to be included in future GDB releases it must be cleanly
-written.  We do not want to include changes that will needlessly make future
-maintainance difficult.  It is not much harder to do things right, and
-in the long term it is worth it to the GNU project, and probably to
-you individually as well.
-
-Please code according to the GNU coding standards.  If you do not have
-a copy, you can request one by sending mail to gnu@prep.ai.mit.edu.
-
-Please try to avoid making machine-specific changes to
-machine-independent files (i.e. all files except "param.h" and
-"dep.c".  "pinsn.c" and "opcode.h" are processor-specific but not
-operating system-dependent).  If this is unavoidable, put a hook in
-the machine-independent file which calls a (possibly)
-machine-dependent macro (for example, the IGNORE_SYMBOL macro can be
-used for any symbols which need to be ignored on a specific machine.
-Calling IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of #if
-defined's).  The machine-independent code should do whatever "most"
-machines want if the macro is not defined in param.h.  Using #if
-defined can sometimes be OK (e.g.  SET_STACK_LIMIT_HUGE) but should be
-conditionalized on a specific feature of an operating system (set in
-param.h) rather than something like #if defined(vax) or #if
-defined(SYSV).
-
-It is better to replace entire routines which may be system-specific,
-rather than put in a whole bunch of hooks which are probably not going
-to be helpful for any purpose other than your changes.  For example,
-if you want to modify dbxread.c to deal with DBX debugging symbols
-which are in COFF files rather than BSD a.out files, do something
-along the lines of a macro GET_NEXT_SYMBOL, which could have
-different definitions for COFF and a.out, rather than trying to put
-the necessary changes throughout all the code in dbxread.c that
-currently assumes BSD format.
-
-Please avoid duplicating code.  For example, if something needs to be
-changed in read_inferior_memory, it is very painful because there is a
-copy in every dep.c file.  The correct way to do this is to put (in
-this case) the standard ptrace interfaces in a separate file ptrace.c,
-which is used by all systems which have ptrace.  ptrace.c would deal
-with variations between systems the same way any system-independent
-file would (hooks, #if defined, etc.).
-
-About debugging gdb with itself...
-
-You probably want to do a "make TAGS" after you configure your
-distribution; this will put the machine dependent routines for your
-local machine where they will be accessed first by a M-period .
-
-Also, make sure that you've compiled gdb with your local cc or taken
-appropriate precautions regarding ansification of include files.  See
-the Makefile for more information.
-
-The "info" command, when executed without a subcommand in a gdb being
-debugged by gdb, will pop you back up to the top level gdb.  See
-.gdbinit for more details.
