-Midi2ly translates a MIDI input file to a LilyPond source file. MIDI
-(Music Instrument Digital Interface) is a standard for digital
-instruments: it specifies cabling, a serial protocol and a file format.
+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.
-The MIDI file format is a de facto standard format for exporting music
-from other programs, so this capability may come in useful when you want
-to import files from a program that has no converter for its native
-format.
+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
-It is possible to record a MIDI file using a digital keyboard, and then
-convert it to @file{.ly}. However, human players are not rhythmically
-exact enough to make a MIDI to LY conversion trivial. midi2ly tries to
-compensate for these timing errors, but is not very good at this. It is
-therefore not recommended to use midi2ly for human-generated midi
-files. Correcting the quantization mistakes of the human player takes a
-lot of time.
+@example
+covert-ly -e MYFILE.ly
+@end example
-Hackers who know about signal processing are invited to write a more
-robust midi2ly. midi2ly is written in Python, using a module written in
-C to parse the MIDI files.
+If there are no changes to MYFILE.ly and if a file called MYFILE.ly.NEW
+is created, then MYFILE.ly is already updated.
+To upgrade LilyPond fragments in texinfo files, use

-@unnumberedsubsec Options

-@item -h, --help,
- Show a summary of usage.
-@item -I, --include=@file{DIR},
- Add DIR to search path.
-@item -k, --key=ACC[:MINOR],
- Set default key. ACC > 0 sets number of sharps; ACC < 0 sets number
- of flats. A minor key is indicated by ":1".
-@item -n, --no-silly,
- Assume no plets or double dots, assume smallest (reciprocal) duration 16.
-@item -o, --output=@file{FILE},
- Set @file{FILE} as default output.
-@item -p, --no-plets,
- Assume no plets.
-@item -q, --quiet,

-@item -s, --smallest=N,
- Assume no shorter (reciprocal) durations than N.
-@item -v, --verbose,
- Be verbose.
-@item -w, --warranty,
- Show the warranty with which midi2ly comes. (It comes with @strong{NO WARRANTY}!)
-@item -x, --no-double-dots,
- Assume no double dotted notes.
+@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.
