The @code{--safe} option works by evaluating in-line Scheme

-LilyPond API. These functions are listed in @file{scm/safe-lily.scm}.

+into Scheme.
+
+@code{--safe} does @emph{not} detect resource overuse. It is still
+possible to make the program hang indefinitely, for example by feeding
+cyclic data structures into the backend. Therefore, if using LilyPond
+on a publicly accessible webserver, the process should be limited in
+both CPU and memory usage.
+
+Note that @code{--safe} will prevent many useful LilyPond snippets from
+being compiled. For a softer but secure alternative you can use the
+@code{--jail} option.
+
+
+@item -j,--jail=@var{user},@var{group},@var{jail},@var{dir}
+Run LilyPond in a chroot jail.
+
+The @code{--jail} option provides a more flexible alternative to
+@code{--safe} when LilyPond formatting is available through a web
+server or whenever LilyPond executes externally provided
+sources.
+
+The @code{--jail} option works by changing the root of LilyPond to
+@var{jail} just before starting the actual compilation process. The user
+and group are then changed to match those provided, and the current
+directory is changed to @var{dir}. This setup guarantees that it is not
+possible (at least in theory) to escape from the jail. Note that for
+@code{--jail} to work LilyPond must be run as root, which is usually
+accomplished in a safe way using @command{sudo}.
+
+Setting up a jail is a slightly delicate matter, as we must be sure that
+LilyPond is able to find whatever it needs to compile the source
+@emph{inside the jail}. A typical setup comprises the following items:
+
+@table @asis
+@item Setting up a separate filesystem
+A separate filesystem should be created for LilyPond, so that it can be
+mounted with safe options such as @code{noexec}, @code{nodev}, and
+@code{nosuid}. In this way, it is impossible to run executables or to
+write directly to a device from LilyPond. If you do not want to create a
+separate partition, just create a file of reasonable size and use it to
+mount a loop device. A separate filesystem also guarantees that LilyPond
+cannot write more space than it is allowed.
+
+@item Setting up a separate user
+A separate user and group (say, @samp{lily}/@samp{lily}) with low
+privileges should be used to run LilyPond inside the jail. There should
+be a single directory writable by this user, which should be passed in
+@var{dir}.
+
+@item Preparing the jail
+LilyPond needs to read a number of files while running. All these files
+are to be copied into the jail, under the same path they apper in the
+real root filesystem. The entire content of the LilyPond installation
+(e.g., @file{/usr/share/lilypond})
+should be copied.
+
+If problems arise, the simplest way to trace them down is to run
+LilyPond using @command{strace}, which will allow you to determine which
+files are missing.
+
+@item Running LilyPond
+In a jail mounted with @code{noexec} it is impossible to execute any external
+program. Therefore LilyPond must be run with a backend that does not
+require any such program. As we already mentioned, it must be also run
+with superuser privileges (which, of course, it will lose immediately),
+possibly using @command{sudo}. It is a good idea to limit the number of
+seconds of CPU time LilyPond can use (e.g., using @command{ulimit
+-t}), and, if your operating system supports it, the amount of memory
+that can be allocated.

+@section Updating with @command{convert-ly}
+
+@cindex Updating a LilyPond file
+@cindex @code{convert-ly}
+
+The LilyPond input syntax is routinely changed to simplify it or improve
+it in different ways. As a side effect of this, the LilyPond interpreter
+often is no longer compatible with older input files. To remedy this,
+the program @command{convert-ly} can be used to deal with most of the
+syntax changes between LilyPond versions.
+
+It uses @code{\version} statements in the input files to detect the
+old version number. In most cases, to upgrade your input file it is
+sufficient to run@footnote{MacOS X users may execute this command
+under the menu entry @samp{Compile > Update syntax}.}
+
+@example
+convert-ly -e myfile.ly
+@end example
+
+If there are no changes to myfile.ly and file called myfile.ly.NEW
+is created, then myfile.ly is already updated.
+
+@command{convert-ly} always converts up to the last syntax change handled by
+it. This means that the @code{\version} number left in the file is
+usually lower than the version of @command{convert-ly} itself.
+
+To upgrade LilyPond fragments in texinfo files, use
+
+@example
+convert-ly --from=... --to=... --no-version *.itely
+@end example
+
+To upgrade many files at once, combine @code{convert-ly} with
+standard unix commands. This example will upgrade all @code{.ly}
+files in the current directory
+
+@example
+for f in *.ly; do convert-ly -e $f; done;
+@end example
+
+In general, the program is invoked as follows:
+
+@example
+convert-ly [@var{option}]@dots{} @var{file}@dots{}
+@end example
+
+
+The following options can be given:
+
+@table @code
+@item -e,--edit
+Do an inline edit of the input file. Overrides @code{--output}.
+
+@item -f,--from=@var{from-patchlevel}
+Set the version to convert from. If this is not set, @command{convert-ly}
+will guess this, on the basis of @code{\version} strings in the file.
+
+@item -n,--no-version
+Normally, @command{convert-ly} adds a @code{\version} indicator
+to the output. Specifying this option suppresses this.
+
+@item -s, --show-rules
+Show all known conversions and exit.
+
+@item --to=@var{to-patchlevel}

+There are a few things that the convert-ly cannot handle. Here's a list of limitations

+here for reference.
+
+1.6->2.0:
+ Doesn't always convert figured bass correctly, specifically things like {< >}. Mats' comment on working around this:
+ To be able to run convert-ly
+ on it, I first replaced all occurencies of '{<' to some dummy like '{#'
+ and similarly I replaced '>}' with '&}'. After the conversion, I could
+ then change back from '{ #' to '{ <' and from '& }' to '> }'.
+ Doesn't convert all text markup correctly. In the old markup syntax,
+ it was possible to group a number of markup commands together within parentheses, e.g.
+ -#'((bold italic) "string")
+ This will incorrectly be converted into
+ -\markup{{\bold italic} "string"}
+ instead of the correct
+ -\markup{\bold \italic "string"}
+2.0->2.2:
+ Doesn't handle \partcombine
+ Doesn't do \addlyrics => \lyricsto, this breaks some scores with multiple stanzas.
+2.0->2.4:
+ \magnify isn't changed to \fontsize.
+ - \magnify #m => \fontsize #f, where f = 6ln(m)/ln(2)
+ remove-tag isn't changed.
+ - \applyMusic #(remove-tag '. . .) => \keepWithTag #'. . .
+ first-page-number isn't changed.
+ - first-page-number no => printfirst-page-number = ##f
+ Line breaks in header strings aren't converted.
+ - \\\\ as line break in \header strings => \markup \center-align <
+ "First Line" "Second Line" >
+ Crescendo and decrescendo terminators aren't converted.
+ - \rced => \!
+ - \rc => \!
+2.2->2.4:
+ \turnOff (used in \set Staff.VoltaBracket = \turnOff) is not properly converted.
+2.4.2->2.5.9
+ \markup{ \center-align <{ ... }> } should be converted to:

-
-@cindex stdin, reading
-
-@table @code
-@item -k,--keep
- Keep the temporary directory with all output
-files. The temporary directory is created in the current directory as @code{@code{lilypond}.dir}.
-@item -h,--help
- Print usage help.
-@item -I,--include=@var{dir}
- Add @var{dir} to LilyPond's include path.
-@item -o,--output=@var{file}
- Generate output to @var{file}. The extension of @var{file} is ignored.
-@item --png

-@item -s,--set=@var{key}=@var{val}
- Add @var{key}= @var{val} to the settings, overriding those specified
-in the files. Possible keys: @code{language}, @code{latexheaders},
-@code{latexpackages}, @code{latexoptions}, @code{papersize},
-@code{linewidth}, @code{orientation},
-@code{textheight}.
-@item -v,--version
-Show version information.
-@item -V,--verbose
-Be verbose. This prints out commands as they are executed, and more
-information about the formatting process is printed.

-@subsection Additional parameters
-
-The @code{lilypond} program responds to several parameters specified
-in a @code{\layout} section of the input file. They can be overridden
-by supplying a @code{--set} command line option.
-
-@table @code
-@item language
- Specify La@TeX{} language: the @code{babel} package will be
-included. Default: unset.
-
- Read from the @code{\header} block.
-
-@item latexheaders
- Specify additional La@TeX{} headers file.
- Normally read from the @code{\header} block. Default value: empty.
-
-@item latexpackages
- Specify additional La@TeX{} packages file. This works cumulative,
-so you can add multiple packages using multiple @code{-s=latexpackages} options.
- Normally read from the @code{\header} block. Default value:
-@code{geometry}.
-
-@item latexoptions
- Specify additional options for the La@TeX{}
-@code{\documentclass}. You can put any valid value here. This was
-designed to allow @code{lilypond} to produce output for double-sided
-paper, with balanced margins and page numbers on alternating sides. To
-achieve this specify @code{twoside}.
-
-@item orientation
- Set orientation. Choices are @code{portrait} or @code{landscape}. Is
-read from the @code{\layout} block, if set.
-
-@item textheight
- The vertical extension of the music on the page. It is normally
- calculated automatically, based on the paper size.
-
-@item linewidth
- The music line width. It is normally read from the @code{\layout}
-block.
-
-@item papersize
- The paper size (as a name, e.g. @code{a4}). It is normally read from
-the @code{\layout} block.
-
-@item fontenc
- The font encoding, should be set identical to the @code{font-encoding}
- property in the score.
