-@node Building LilyPond
-@subsection Building LilyPond
-
-@unnumberedsubsubsec Compiling
-
-To install GNU LilyPond, type
-
-@example
-gunzip -c lilypond-x.y.z | tar xf -
-cd lilypond-x.y.z
-./configure # run with --help for applicable options
-make
-su -c 'make install'
-@end example
-
-@noindent
-If you are not root, you should choose a @code{--prefix} argument that
-points into your home directory, e.g.
-
-@example
-./configure --prefix=$HOME/usr
-@end example
-
-
-@unnumberedsubsubsec Compiling for multiple platforms
-
-If you want to build multiple versions of LilyPond with different
-configuration settings, you can use the @code{--enable-config=CONF}
-option of @command{configure}. You should use @code{make conf=CONF}
-to generate the output in @file{out-CONF}. For example, suppose you
-want to build with and without profiling, then use the following for
-the normal build
-
-@example
-./configure --prefix=$HOME/usr/ --enable-checking
-make
-make install
-@end example
-
-and for the profiling version, specify a different configuration
-
-@example
-./configure --prefix=$HOME/usr/ --enable-profiling --enable-config=prof --disable-checking
-make conf=prof
-make conf=prof install
-@end example
-
-
-@unnumberedsubsubsec Compiling outside the source tree
-
-It is possible to compile LilyPond in a build tree different from the
-source tree, with @code{--srcdir} option of @command{configure}:
-
-@example
-mkdir lily-build && cd lily-build
-@var{sourcedir}/configure --srcdir=@var{sourcedir}
-
-@end example
-
-
-@unnumberedsubsubsec Useful @command{make} variables
-
-If a less verbose build output if desired, the variable
-@code{QUIET_BUILD} may be set to @code{1} on @command{make} command
-line, or in @file{local.make} at top of the build tree.

-@node Building documentation
-@subsection Building documentation
-
-This requires a successful compile of LilyPond, or using an external
-LilyPond binary.
-
-@menu
-* Commands for building documentation:: Compiling and installing the documentation.
-* Building documentation without compiling LilyPond:: Using a LilyPond binary already installed.
-@end menu
-
-@node Commands for building documentation
-@unnumberedsubsubsec Commands for building documentation
-
-The documentation is built by issuing
-
-@example
-make web
-@end example
-
-After compilation, the HTML documentation tree is available in
-@file{out-www/offline-root/}, and can be browsed locally.
-
-The HTML and PDF files can be installed into the standard documentation
-path by issuing
-
-@example
-make web-install
-@end example
-
-@noindent
-This also installs Info documentation with images if the installation
-prefix is properly set; otherwise, instructions for manual installation
-of Info documentation are printed on standard output.
-
-It is also possible to build a documentation tree in
-@file{out-www/online-root/}, with special processing, so it can be used
-on a website with content negotiation for automatic language selection;
-this can be achieved by issuing
-
-@example
-make WEB_TARGETS=online web
-@end example
-
-@noindent
-and both @q{offline} and @q{online} targets can be generated by issuing
-
-@example
-make WEB_TARGETS="offline online" web
-@end example
-
-Several targets are available to clean the documentation build and
-help with maintaining documentation; an overview of these targets is
-available with
-
-@example
-make help
-@end example
-
-@noindent
-from every directory in the build tree. Most targets for
-documentation maintenance are available from @file{Documentation/};
-for more information, see @file{Documentation/user/README.txt} and
-@file{Documentation/TRANSLATION}.
-
-The makefile variable @code{QUIET_BUILD} may be set to @code{1} for a
-less verbose build output, just like for building the programs.
-
-@knownissues
-
-The most time consuming task for building the documentation is running
-LilyPond to build images of music, and there cannot be several
-simultaneously running @command{lilypond-book} instances, so @code{-j}
-@command{make} option does not significantly speed up the build process.
-To help speed it up, the makefile variable @var{CPU_COUNT} may be set
-in @file{local.make} or on the command line to the number of
-@code{.ly} files that LilyPond should process simultaneously, e.g. on
-a bi-processor or dual core machine
-
-@example
-make -j3 CPU_COUNT=3 web
-@end example
-
-@noindent
-The recommended value of @var{CPU_COUNT} is one plus the number of
-cores or processors, but it is advisable to set it to a smaller value
-if your system has not enough RAM to run that many simultaneous
-LilyPond instances.
-
-If source files have changed since last documentation build, output
-files that need to be rebuilt are normally rebuilt, even if you do not
-run @code{make web-clean} first. However, building dependencies in the
-documentation are so complex that rebuilding of some targets may not
-be triggered as they should be; a workaround is to force rebuilding
-by touching appropriate files, e.g.
-
-@example
-touch Documentation/user/*.itely
-touch input/lsr/*.ly
-@end example
-
-
-@node Building documentation without compiling LilyPond
-@unnumberedsubsubsec Building documentation without compiling LilyPond
-
-The documentation can be built locally without compiling LilyPond
-binary, if LilyPond is already installed on your system.
-
-From a fresh Git checkout, do
-
-@example
-./autogen.sh # ignore any warning messages
-cp GNUmakefile.in GNUmakefile
-make -C python
-nice make LILYPOND_EXTERNAL_BINARY=/path/to/bin/lilypond web
-@end example
-
-Please note that this may break sometimes -- for example, if a new
-feature is added with a test file in input/regression, even the latest
-development release of LilyPond will fail to build the docs.
-
-You may build the manual without building all the @file{input/*}
-stuff: change directory, for example to @file{Documentation/user},
-issue @code{make web}, which will build documentation in a
-subdirectory @file{out-www} from the source files in current
-directory. In this case, if you also want to browse the documentation
-in its post-processed form, change back to top directory and issue
-
-@example
-make out=www WWW-post
-@end example
-
-@knownissues
-
-You may also need to create a script for @command{pngtopnm} and
-@code{pnmtopng}. On GNU/Linux, I use this:
-
-@verbatim
-export LD_LIBRARY_PATH=/usr/lib
-exec /usr/bin/pngtopnm "$@"
-@end verbatim
-
-On MacOS@tie{}X, I use this:
-
-@verbatim
-export DYLD_LIBRARY_PATH=/sw/lib
-exec /sw/bin/pngtopnm "$@"
-@end verbatim

-LilyPond comes with an extensive suite that exercises the entire
