@node Running lilypond
The @code{-dsafe} option works by evaluating in-line Scheme
expressions in a special safe module. This safe module is derived from
GUILE @file{safe-r5rs} module, but adds a number of functions of the
-LilyPond API. These functions are listed in @file{scm/@/safe@/-lily@/.scm}.
+LilyPond API. These functions are listed in @file{scm/safe-lily.scm}.
In addition, safe mode disallows @code{\include} directives and
disables the use of backslashes in @TeX{} strings.
The @code{ps}, @code{eps}, and @code{svg} backends support this
option.
+@item gui
+Runs silently and redirect all output to a log file.
+
+Note to Windows users: By default @code{lilypond.exe} outputs all
+progress information to the command window, @code{lilypond-windows.exe}
+does not and returns a prompt, with no progress information, immediately
+at the command line. The @code{-dgui} option can be used in this case
+to redirect output to a log file.

@item print-pages
Generate the full pages, the default. @code{-dno-print-pages} is
useful in combination with @code{-dpreview}.
@item -i,--init=@var{file}
Set init file to @var{file} (default: @file{init.ly}).
+@cindex loglevel
+@cindex output verbosity, setting
+
+@item -l,--loglevel=@var{LEVEL}
+Set the verbosity of the console output to @var{LEVEL}. Possible values are:
+@table @code
+@item NONE
+No output at all, not even error messages.
+
+@item ERROR
+Only error messages, no warnings or progress messages.
+
+@item WARN
+Warnings and error messages, no progress.
+
+@item BASIC_PROGRESS
+Basic progress messages (success), warnings and errors.
+
+@item PROGRESS (default)
+All progress messages, warnings and errors.
+
+@item DEBUG
+All possible messages, including verbose debug output.

@cindex folder, directing output to
@cindex output filename, setting
@item LANG
This selects the language for the warning messages.
+@item LILYPOND_LOGLEVEL
+The default loglevel. If LilyPond is called without an explicit loglevel (i.e.
+no @code{--loglevel} command line option), this value is used.

-With this variable the memory footprint and performance can be
-adjusted. It is a percentage tunes memory management behavior. With
-higher values, the program uses more memory, with smaller values, it
-uses more CPU time. The default value is @code{70}.
+A variable, as a percentage, that tunes memory management

@unnumberedsubsec Apparent error in @code{../ly/init.ly}
Various obscure error messages may appear about syntax errors in
-@code{../ly/init.ly} if the input file is not correctly formed,
+@file{../ly/init.ly} if the input file is not correctly formed,
for example, if it does not contain correctly
matched braces or quote signs.
