As much as I'd love to take some credit here, I very much doubt that
it was our influence. Synedra is a relatively recent project. Soft
locks and compounds are both bits of database terminology that were
appropriated by the SCM community. I can definitively date soft locks
in SCM systems back at least 15 years... And compounds, AKA
at least 10 years. Synedra handles both of them differently from
a lot of conventional systems.

I'll try to put together a doc on how we handle subprojects,
and get it posted on our webpage, right after I finish with
this messy change I'm working on. Maybe that can give you
some good ideas of how to approach it.
