; Change History (most recent first):
;
; <3> 8/12/93 kc <mb>: I deleted all of the "TheFuture" conditionals in all of
; the CommToolbox files per Mike Bell's instructions. I also had
; to delete some old code that was compiled under the "CubeE"
; conditional.
; <4> 6/8/92 JSM For TheFuture, check emProcessMgrExists instead of Gestalt to
; test for the existence of the Process Mgr. Doesnt really
; matter, since this file isnt used in any builds??
; <3> 7/10/91 BH better patch (all three rolled into a single patch)
; <2> 7/10/91 BH add fix to CRMGetHeader
; <1> 7/9/91 BH first checked in
;
