LAAS - lilypond as a service

[noteflakes]

Features:

• A server offering a lilypond compilation service - user uploads a snippet or a complete file or a complete file archive including all dependencies, the server generates the target file.
• Support for all applicable command line switches (i.e. relating to output).
• Support for different version of lilypond.
• Support for lyp packages (as long as they can be found - those on the lyp package index, or those with a URL).
• Should be fast (as possible).
• Should cache output files on disk (in /tmp perhaps?).

Additional tooling:

• Linux/MacOS - bash script for compiling from shell.
• Windows - batch file for compiling from shell.

What needs to be added to lyp?

• HTTP server (on arbitrary port) and accept HTTP requests for compiling files, along with command line arguments.
• Cache output file (hash input files and command line arguments) in /tmp.
• Automatic installation of requested lilypond version, if not already installed.
• Process separation to limit security exposure (use lys?)

Another possibility is to create an external tool that will use lyp as a ruby dependency (actually an interesting use case).
