    NAME
         lxref - lisp cross reference program

    SYNOPSIS
         lxref [ -N ] xref-file ...  [ -a source-file ... ]

    DESCRIPTION
         Lxref reads cross reference file(s) written by the lisp com-
         piler liszt and prints a cross reference listing on the
         standard output.  Liszt will create a cross reference file
         during compilation when it is given the -x switch.  Cross
         reference files usually end in `.x' and consequently lxref
         will append a `.x' to the file names given if necessary.
         The first option to lxref is a decimal integer, N, which
         sets the ignorelevel. If a function is called more than
         ignorelevel times, the cross reference listing will just
         print the number of calls instead of listing each one of
         them.  The default for ignorelevel is 50.

         The -a option causes lxref to put limited cross reference
         information in the sources named.	lxref will scan the
         source and when it comes across a definition of a function
         (that is a line beginning with `(def' it will preceed that
         line with a list of the functions which call this function,
         written as a comment preceeded by `;.. ' . All existing
         lines beginning with `;.. ' will be removed from the file.
         If the source file contains a line beginning `;.-' then this
         will disable this annotation process from this point on
         until a `;.+' is seen (however, lines beginning with `;.. '
         will continue to be deleted).  After the annoation is done,
         the original file `foo.l' is renamed to " `#.foo.l'" and the
         new file with annotation is named `foo.l'
