what is XCL?

[Sam S. <sd...@gn...>]

Hi Bruno,
CLISP test suite mentions XCL a lot.
Moreover, it contains 3 files (readtable, tread, tprint) which are
_only_ used with XCL.
Comments seem to indicate that XCL might be a German implementation from
the 1980-ies.

Could you please shed some light on this?
Do we need it?

Thanks.
