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 compiler 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  conse‐
       quently  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
