Converting from MusicXML to Lilypond format

[David Bolton]

I would like to convert MusicXML files to lilypond format on Microsoft Windows.

About a year ago when I was starting to familiarize myself with lilypond, the 
program opened up a command-line screen where you could type something like: 

musicxml --output=C:\example_music.xml C:\example_music.lp

and it would convert the file. Now the program does not come up with a 
command=line screen (it has a welcome screen instead), so where do I go to 
type the information above?

The documentation is of no help:

formats.html#Converting-from-other-formats

I appreciate any help,
