;;; Apr-14 -- clm-5 (remove framples and mixers)
;;; Feb-08 -- clm-4 (new gens, etc)
;;; Jul-04 -- clm-3 (use clm.c)
;;; Mar-00 -- sndlib internal sample representation is now configurable, so clm has to reflect that.
;;; Jul-99 -- C side uses doubles throughout, Lisp side uses CLOS
;;; Jun-99 -- clm-2 name changes, run-time types -- everything changed!
;;; Jul-98 -- serious bug in readin forced me to change its layout, rippling through several other gens.
;;; Jun-98 -- _c names removed from cmus0.lisp, and Mac calloc/free replaced by NewPtr/DisposePtr
;;; Apr-98 -- many MCL changes
;;; Mar-98 -- higher precision clm_env causes layout changes
;;; Jul-97 -- no-rld linker support removed -- many prototype changes
;;; Oct-95 -- many changes for n-channel IO and run-block connections to src et al
;;; Jul-95 -- array allocation changed for SGI port
;;; Apr-95 -- boolean handling completely revised.
;;; Oct-94 -- parallel instrument scheduling option.
;;; Mar-94 -- full C output, rather than heavy use of foreign function interface
;;; Nov-93 -- array version
;;; Mar-93 -- struct version
;;; 1990 -- initial clm implementation from mus10/sambox
