+@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.

+* 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 "$@"
+@end verbatim
+
+On MacOS@tie{}X, I use this:
+
+@verbatim
+export DYLD_LIBRARY_PATH=/sw/lib
+exec /sw/bin/pngtopnm "$@"

+@node Testing LilyPond
+@subsection Testing LilyPond
+
+@html
+<a name="testing"></a>
+@end html
+
+LilyPond comes with an extensive suite that exercises the entire
+program. This suite can be used to automatically check the impact of a
+change. This is done as follows
+
+@example
+make test-baseline
+@emph{## apply your changes, compile}
+make check
+@end example
+
+This will leave an HTML page @file{out/test-results/index.html}. This
+page shows all the important differences that your change introduced,
+whether in the layout, MIDI, performance or error reporting.
+
+To rerun tests, use
+
+@example
+make test-redo @emph{## redo files differing from baseline}
+make test-clean @emph{## remove all test results}
+@end example
+
+@noindent
+and then run @code{make check} again.
+
+For tracking memory usage as part of this test, you will need GUILE
+CVS; especially the following patch:
+@uref{http://lilypond.org/vc/gub.darcs/patches/guile-1.9-gcstats.patch}.
+
+For checking the coverage of the test suite, do the following
+
+@example
+./scripts/auxiliar/build-coverage.sh
+@emph{# uncovered files, least covered first}
+./scripts/auxiliar/coverage.py --summary out-cov/*.cc
+@emph{# consecutive uncovered lines, longest first}
+./scripts/auxiliar/coverage.py --uncovered out-cov/*.cc

+
+Bugs that are not fault of LilyPond are documented here.
+
+@unnumberedsubsubsec Bison 1.875
+
+There is a bug in bison-1.875: compilation fails with "parse error
+before `goto'" in line 4922 due to a bug in bison. To fix, please
+recompile bison 1.875 with the following fix
+
+@example
+$ cd lily; make out/parser.cc
+$ vi +4919 out/parser.cc
+# append a semicolon to the line containing "__attribute__ ((__unused__))
+# save
+$ make
+@end example
+
+
+@unnumberedsubsubsec Solaris
+
+Solaris7, ./configure
+
+@file{./configure} needs a POSIX compliant shell. On Solaris7,
+@file{/bin/sh} is not yet POSIX compliant, but @file{/bin/ksh} or bash
+is. Run configure like
+
+@example
+CONFIG_SHELL=/bin/ksh ksh -c ./configure
+@end example
+
+@noindent
+or
+
+@example
+CONFIG_SHELL=/bin/bash bash -c ./configure
+@end example
+
+@unnumberedsubsubsec FreeBSD
+
+To use system fonts, dejaview must be installed. With the default
+port, the fonts are installed in @file{usr/X11R6/lib/X11/fonts/dejavu}.
+
+Open the file @file{$LILYPONDBASE/usr/etc/fonts/local.conf} and add the
+following line just after the @code{<fontconfig>} line. (Adjust as necessary
+for your hierarchy.)
+
+@example
+<dir>/usr/X11R6/lib/X11/fonts</dir>
+@end example
+
+
+@unnumberedsubsubsec International fonts
+
+On MacOS@tie{}X, all fonts are installed by default. However, finding all
+system fonts requires a bit of configuration; see
+@uref{http://lists.gnu.org/archive/html/lilypond-user/2007-03/msg00472.html,
+this post} on the @code{lilypond-user} mailing list.
+
+On Linux, international fonts are installed by different means on
+every distribution. We cannot list the exact commands or packages
+that are necessary, as each distribution is different, and the exact
+package names within each distribution changes. Here are some
+hints, though:
