To run LilyPond on AWS Lambda for LilyBin, I need to upload a zip file containing the LilyPond executable and assets, and it must be no larger than 50 MB. Recent versions of LilyPond unstable are about 52 MB zipped (zip -r9). Are there any large files in the installation directory I can delete without breaking anything? Or maybe I could compress executables better than zip does?
Here's the sorted output of du -ah:
