+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice

+UNCOMPRESSING .tgz FILES
+===========================
+Many of the files found in this directory and its subdirectories 
+are gzip'ed, tar archive files.  These files have the ".tgz"
+extension.  They were compressed with gzip version 1.2.4.  
+
+Use a command sequence similar to the following to uncompress each
+file:
+
+   gzcat FILE.tgz | tar xvof -
+
+where FILE.tgz is the file to be installed.  This procedure will
+extract the files in the archive into the current directory.
+All of the .tgz files associated with this release RTEMS will
+place their contents in a subdirectory rtems-<release> in the current
+directory.
+
+If you are unsure of what is in an RTEMS archive file, then use
+the following command sequence to get a listing of the contents:
+
+   gzcat FILE.tgz | tar tvf -
+
+NOTES:  
+
+(1) The "-o" option to tar is included on the tar command line
+    so that the user extracting the tar archive will own the extracted
+    files.
+
+(2) gzcat is sometimes installed as zcat.  Be warned that on many
+    (most) UNIX machines, zcat is associated with compress (.Z files).
+
+(3) If you do not have gzip 1.2.4, it is available from numerous sites
+    including this one.  Other sites include ftp.gnu.org and ftp.cdrom.com.
+    
+(4) The GNU archive files included in this distribution are packaged
+    exactly like they are on official GNU ftp sites.  When extracting
+    GNU archives, they will not extract under a rtems-<version> 
+    directory.  They will extract themselves under a directory which
+    is the name and version of the tool in question.  For example,
+    gcc-2.5.8.tgz will extract its contents into the subdirectory 
+    gcc-2.5.8.

+Directory Overview
+==================
+
+This is the top level of the RTEMS directory structure.  The following 
+is a description of the files and directories in this directory:
+
+  INSTALL
+    Rudimentary installation instructions.  For more detailed
+    information please see the Release Notes.  The Postscript 
+    version of this manual can be found in the file

+    This file.
+
+  c
+    This directory contains the source code for the C 
+    implementation of RTEMS as well as the test suites, sample 
+    applications, Board Support Packages, Device Drivers, and 
+    support libraries.
+
+  doc
+    This directory contains the PDL for the RTEMS executive.
+
+Ada versus C
+============
+
+There are two implementations of RTEMS in this source tree -- 
+in Ada and in C.  These two implementations are functionally
+and structurally equivalent.  The C implementation follows
+the packaging conventions and hiearchical nature of the Ada 
+implementation.  In addition, a style has been followed which 
+allows one to easily find the corresponding Ada and C 
+implementations.  
+
+File names in C and code placement was carefully designed to insure
+a close mapping to the Ada implementation.  The following file name 
+extensions are used:
+
+   .adb - Ada body
+   .ads - Ada specification
+   .adp - Ada body requiring preprocessing
+   .inc - include file for .adp files
+
+   .c   - C body (non-inlined routines)
+   .inl - C body (inlined routines)
+   .h   - C specification
+
+In the executive source, XYZ.c and XYZ.inl correspond directly to a 
+single XYZ.adb or XYZ.adp file.  A .h file corresponds directly to
+the .ads file.  There are only a handful of .inc files in the 
+Ada source and these are used to insure that the desired simple 
+inline textual expansion is performed.  This avoids scoping and
+calling convention side-effects in carefully constructed tests 
+which usually test context switch behavior.
+
+In addition, in Ada code and data name references are always fully
+qualified as PACKAGE.NAME.  In C, this convention is followed 
+by having the package name as part of the name itself and using a
+capital letter to indicate the presence of a "." level.  So we have
+PACKAGE.NAME in Ada and _Package_Name in C.  The leading "_" in C
+is used to avoid naming conflicts between RTEMS and user variables.
+By using these conventions, one can easily compare the C and Ada
+implementations.
+
+The most noticeable difference between the C and Ada83 code is 
+the inability to easily obtain a "typed pointer" in Ada83.  
+Using the "&" operator in C yields a pointer with a specific type.
+The 'Address attribute is the closest feature in Ada83.  This
+returns a System.Address and this must be coerced via Unchecked_Conversion
+into an access type of the desired type.  It is easy to view 
+System.Address as similar to a "void *" in C, but this is not the case.
+A "void *" can be assigned to any other pointer type without an
+explicit conversion.  
+
+The solution adopted to this problem was to provide two routines for
+each access type in the Ada implementation -- one to convert from
+System.Address to the access type and another to go the opposite
+direction.  This results in code which accomplishes the same thing
+as the corresponding C but it is easier to get lost in the clutter
+of the apparent subprogram invocations than the "less bulky"
+C equivalent.
+
+A related difference is the types which are only in Ada which are used 
+for pointers to arrays.  These types do not exist and are not needed 
+in the C implementation.

+1. Autoconf support
+===================
+
+This version of RTEMS is configured with GNU autoconf. RTEMS can be
+configured and built either standalone or together with the compiler
+tools in the Cygnus one-tree structure. Using autoconf also means
+that RTEMS now can be built in a separate build directory.
+
+2. Installation
+===============
+
+2.1 Standalone build
+
+To configure RTEMS for a specific target, run configure in the build
+directory. In addition to the standard configure options, the following
+RTEMS-specific option are supported:
+
+	--disable-rtems-inlines
+	--disable-posix
+	--disable-itron
+	--disable-networking
+        --enable-cxx
+        --enable-bare-cpu-model=<MODEL>
+        --enable-bare-cpu-cflags=<FLAGS>
+        --enable-gcc28               (also use enable-libcdir when disabled)
+        --enable-libcdir=<DIRECTORY>      (do not use if gcc 2.8 is enabled)
+        --enable-multiprocessing
+	--enable-rtemsbsp="bsp1 bsp2 ..."
+	--enable-tests
+	--enable-rdbg            (only valid for i386 and some PowerPC BSPs)
+
+In addition, the following standard autoconf options are frequently
+used when configuring RTEMS installations:
+
+        --prefix=INSTALL_DIRECTORY
+        --program-prefix=
+
+By default, inline routines are used instead of macros where possible.
+Macros can be selected using the --disable-inlines option.  [NOTE:
+Some APIs may not support macro versions of their inline routines.]
+
+By default, the RTEMS POSIX 1003.1b interface is built for targets that support
+it. It can be disabled with the --disable-posix option.
+
+By default, the RTEMS uITRON interface is built for targets that support
+it. It can be disabled with the --disable-itron option.
+
+By default, the RTEMS networking support is built for targets which
+support it.  It can be specifically disabled for those targets
+with the --disable-networking option.
+
+By default, the RTEMS remote debugger server support is not built.
+It can be specifically enabled for the targets that support it.
+with the --enable-rdbg option. NB : the RTEMS networking support
+must be enabled to support the remote debugger server.
+
+By default, the RTEMS support of C++ is disabled.  It can be enabled
+with the --enable-cxx option. If the rtems++ C++ library is installed
+it will also be build.
+
+By default, the RTEMS test suites are NOT configured -- only the 
+sample tests are built.  The --enable-tests will not configure
+the RTEMS test suite. The default speeds up the build
+and configure process when the tests are not desired.
+
+By default, RTEMS is built using arguments and build rules which are 
+NOT compatible with gcc 2.7.2.2.  If using a gcc which supports the
+-specs option, then the --enable-gcc28 option may be used to enable
+this feature.  You should use the --enable-gcc28 option when using
+either the egcs source tree, testgcc snapshots, or gcc 2.8.0 or newer.
+If you --disable-gcc28, then you MUST  specify the location of the
+Standard C Library with the --enable-libcdir option.   [NOTE: These
+options are considered obsolete and may be removed in a future
+RTEMS release.]
+
+By default, multiprocessing is is not built.  It can be enabled
+for those BSPs supporting it by the --enable-multiprocessing option.
+
+By default, all bsps for a target are built. The bare BSP is not built
+unless directlty specified. There are  two ways of changing this:
+
+  + use the --enable-rtemsbsp otion which will set the specified
+    bsps as the default bsps, or 
+  + set the RTEMS_BSP variable during make (see below).
+
+The --enable-rtemsbsp= option configures RTEMS for a specific target
+architecture.  The following targets are supported:
+
+	(none)			will build the host-based version on Linux,
+				Solaris and HPUX.
+
+	a29k-rtems		only standalone, uses non-gnu compiler
+	i386-rtems
+	i960-rtems
+	hppa1.1-rtems
+	m68k-rtems
+	mips64orion-rtems
+        no_cpu-rtems
+	powerpc-rtems
+	sparc-rtems
+        bare                    see notes
+	
+The cross-compiler is set to $(target)-gcc by default. This can be
+overriden by:
+
+  + using the --program-prefix option to configure to specify the
+    string which will prepended to the tool names.  Be sure to include
+    a trailing "-".  For example, to use a m68k-coff toolset, use the
+    --program-prefix=m68k-coff- option.
+
+To build, run make in the build directory. To specify which bsps to build,
+add the RTEMS_BSP="bsp1 bsp2 .." to the make command.  Specifying multiple
+BSPs to build only works from the top level build directory.
+
+Installation is done under $(prefix)/rtems.
+
+As an example, to build and install the mvme136 and dmv152 bsps for m68k do:
+
+	(path_to_rtems_src)/configure --target=m68k-rtems
+
+	make RTEMS_BSP="mvme136 dmv152"
+	
+	make install RTEMS_BSP="mvme136 dmv152"
+
+The sample tests are built by 'make all', do a 'make test' to build the full
+test suite.
+
+2.2 Build with Cygnus one-tree release
+
+To build and install RTEMS with the one-tree structure, just copy the rtems
+directory to the tree. The one-tree configure.in and Makefile.in has to be 
+replaced with the RTEMS-aware versions. The build options are the same as 
+for the standalone build.
+
+2.3 Target Dependent Notes
+
+bare:
+
+  1.  See the README in the bare bsp source directory. This should
+      contain all info you need.
+  2.  The bare bsp source contains a script to show how to build it.
+  3.  The configure flags must be used to get the bare bsp to work.
+      The --enable-bare-cpu-model and --enable-bare-cpu-cflags are the
+      only pieces of information. The module is usually a gcc module
+      such as m68302 or mcpu32. The flags are passed directly to gcc.
+      Use "" if more than one option is specified.
+
+3. To use the installed RTEMS library
+=====================================
+
+To use the installed RTEMS bsps to build applications, the application
+makefile has to include a bsp-specific makefile that will define the
+RTEMS variables necessary to find include files and libraries. The
+bsp-specific makefile is installed at 
+
+	$(RTEMS_MAKEFILE_PATH)/Makefile.inc
+
+For the erc32 bsp installed at /usr/local/cross, the environment
+variable RTEMS_MAKEFILE_PATH would be set as follows to the
+following:
+
+/usr/local/cross/sparc-rtems/rtems/erc32/Makefile.inc
+
+4. Supported target bsps
+========================
+
+The following bsps are supported:
+
+host-based	: posix (on linux, solaris and hpux)
+
+a29k		: portsw
+i386		: i386ex pc386
+i960		: cvme961
+hppa1.1		: simhppa
+m68k		: dmv152 efi332 efi68k gen68302 gen68340 gen68360 
+                  gen68360_040 idp mvme136 mvme147 mvme147s mvme162 ods68302
+no_cpu          : no_bsp
+mips64orion 	: p4600 p4650 (p4000 port with either R4600 or R4650)
+powerpc		: papyrus psim helas403
+sh              : gensh1
+sparc 		: erc32
+any             : bare
+
+5. Makefile structure
+=====================
+
+The makefiles have been re-organised. Most gnu-based bsps now use three
+main makefiles:
+    + custom/default.cfg,
+    + custom/bsp.cfg and
+    + ompilers/gcc-target-default.cfg.
+
+Default.cfg sets the deafult values of certain common build options.
+
+Bsp.cfg set bsp-specific build options and can also override the
+default settings.
+
+Gcc-target-default.cfg contains the common gcc definitions. Some targets
+(a29k, no_cpu, and posix) still use the old structure.
+
+6. Adding a bsp
+===============
+
+The top-level configure.in has to be modified if a new target is added
+or if a new bsp is to be built by default. The additions required is
+basically to add which makefiles are to be created by configure and
+to add the target to the selection statement. To re-generate
+configure, autoconf-2.12 is needed.
+
+7. Tested configurations
+========================
+
+All gnu-based bsps have been built on Linux. 
+The native (posix) ports have been built and run only on Linux.
+
+The following configurations have NOT been tested:
+
+    + Anything on Nextstep, HPUX and Irix.
+    + The a29k port.
+
+8. Pre-requisites
+=================
+
+Gawk version 2 or higher.
+GNU make version 3.72 or higher.
+Bash.
+gcc version ???
+
+TODO
+====
+
+The install-if-change script requires bash. On solaris systems, this should
+be changed to ksh, since ksh is provided with solaris (bash not).
+
+A fairly rescent version of gawk is needed to build RTEMS. This should be
+changed so that a plain vanilla awk also works. [NOTE: This dependency
+should disappear when the "gcc 2.8 -specs" is finished.]
+
+'make install' should only install necessary files, not the full
+PROJECT_RELEASE directory as now.
+
+Posix port on solaris-2.5 fails due to undefined built-in functions
+(gcc-2.7.2, might be my installation).
+
+Improve support for 'make CFLAGS=xxx'.
