Hook like \AtEndDocument

[Urs Liska]

Hi all,

is there a way to hook into the compilation process that allows me to do 
something when all parsing has been done?

Concretely I want to use a Scheme function to collect information during 
the parsing (something like a log) and want to output this in sorted 
form to an external file.

I see two ways to accompish this:

a) write the log to an internal structure, then at the end sort it and 
write it to the file
b) write it to the file immediately and call an external script at the end.

Both approaches (I strongly prefer a) because I'd prefer not to rely on 
an external script) would need a trigger (or listener?) that calls a 
function when everything has been parsed (or when the whole compilation 
process has been finished).
b) could be worked around by wrapping the lilypond call itself into a 
script, but as said I'd prefer a) anyway.

Any ideas?

Thanks
Urs
