SCLF is quite a big utility library (almost 3€ LOC) with limited
portability (CMUCL, SBCL and CLISP to an extent). Continuing to maintain
it is an unnecessary burden, as depot only uses a fraction of it which
is now inlined into the respective users (mime4cl and mblog).
In the future trimming down ex-sclf.lisp may make sense either by
refactoring the code that uses it or by moving interesting utilities
into e.g. klatre.
