-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
-
-@example
-covert-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.
-
-To upgrade LilyPond fragments in texinfo files, use
-
-@example
-convert-ly --from=... --to=... --no-version *.itely
-@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 -o,--output=@var{file}
-Set the output file to write.
-
-@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}
-Set the goal version of the conversion. It defaults to the latest
-available version.
-
-@item -h, --help
-Print usage help.
-@end table
-
-@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.
-
-@refbugs
-
-Not all language changes are handled. Only one output option can be
