Derivation "ATerm" file format

Derivations are serialised in one of the following formats:
-
Derive(...)For all stable derivations.
-
DrvWithVersion(<version-string>, ...)The only
version-strings that are in use today are for experimental features:"xp-dyn-drv"for thedynamic-derivationsexperimental feature.
