    1 ;;; This is asdf: Another System Definition Facility.  $Revision$
    2 ;;;
    3 ;;; Feedback, bug reports, and patches are all welcome: please mail to
    4 ;;; <cclan-list@lists.sf.net>.  But note first that the canonical
    5 ;;; source for asdf is presently the cCLan CVS repository at
    6 ;;; <URL:http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/cclan/asdf/>
    7 ;;;
    8 ;;; If you obtained this copy from anywhere else, and you experience
    9 ;;; trouble using it, or find bugs, you may want to check at the
    10 ;;; location above for a more recent version (and for documentation
    11 ;;; and test files, if your copy came without them) before reporting
    12 ;;; bugs.  There are usually two "supported" revisions - the CVS HEAD
    13 ;;; is the latest development version, whereas the revision tagged
    14 ;;; RELEASE may be slightly older but is considered `stable'
