This chapter details the technicalities of running LilyPond.
-Some of these commands are run from the command-line. By
-@q{command-line}, we mean the command
-line in the operating system. Windows users
-might be more familiar with the terms @q{DOS shell} or
-@q{command shell}; OSX users might be more familiar with the
-terms @q{terminal} or @q{console}. OSX users should also
-consult @ref{MacOS X on the command-line}.
-
-Describing how to use
-this part of an operating system is outside the scope of this
-manual; please consult other documentation on this topic if
-you are unfamiliar with the command-line.
-
-These are separate programs from lilypond itself, and are run
-on the command-line; see @ref{Command-line usage} for more information.

+@var{offending input line}
+@end example
+
+A line-break is inserted in the offending line to indicate the column
+where the error was found. For example,
+
+@example
+test.ly:2:19: error: not a duration: 5:
+ @{ c'4 e'5
+ g' @}
+@end example
+
+These locations are LilyPond's best guess about where the warning or
+error occurred, but (by their very nature) warnings and errors occur
+when something unexpected happens. If you can't see an error in the
+indicated line of your input file, try checking one or two lines
+above the indicated position.

@node Updating files with convert-ly
@section Updating with @command{convert-ly}
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}.}
+sufficient to run
@example
convert-ly -e myfile.ly
@end example
+@noindent
+MacOS X users may execute this command under the menu entry
+@samp{Compile > Update syntax}.
+
If there are no changes to myfile.ly and file called myfile.ly.NEW
is created, then myfile.ly is already updated.
+@subsection Command line options
+
@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.
