bwwtolily will attempt to convert a .bww or .bmw file to a lilypond

(http://lilypond.org) parsable file. Not all of the embellishments
|

get converted properly, this is espessially true with piobaireachd,
|

Convert Bagpipe Reader to Lilypond
|
||||
==================================
|
||||
|
||||
This is a utility to convert a .bww or .bmw file to a [lilypond](https://lilypond.org) parsable file.
|
||||
Not all of the embellishments get converted properly, this is espessially true with piobaireachd,
|
||||
and the program will list the embellishments that were not converted.
|
||||
|
||||
If you recognize an embellishment that isn't being parsed, please
|
||||
send an email regarding the embellishment to jezra@jezra.net and I
|
||||
will try to add the embellishment to the application.
|
||||
create an [issue on github](https://github.com/kastdeur/bwwtolily/issues)
|
||||
|
||||
usage:
|
||||
>bwwtolily -i /path/to/a/bww/file
|
||||
```
|
||||
$ bwwtolily /path/to/a/bww/file
|
||||
```
|
||||
|
||||
optionally, using the "-l" flag will try to run lilypond on the
|
||||
created .ly file
|
||||
example:
|
||||
>bwwtolily -i /path/to/bww/file -l
|
||||
|
||||
```
|
||||
$ bwwtolily /path/to/bww/file -l
