       lndir  -	 create	a shadow directory of symbolic links to	another	direc-
       tory tree

       lndir [ -silent ] [ -ignorelinks	] [ -withrevinfo ] fromdir [ todir ]

       The lndir program makes	a  shadow  copy	 todir	of  a  directory  tree
       fromdir,	 except	 that  the shadow is not populated with	real files but
       instead with symbolic links pointing at the real	files in  the  fromdir
       directory tree.	This is	usually	useful for maintaining source code for
       different machine architectures.	 You create a  shadow  directory  con-
       taining	links  to the real source, which you will have usually mounted
       from a remote machine.  You can build in	the shadow tree, and  the  ob-
       ject  files  will be in the shadow directory, while the source files in
       the shadow directory are	just symlinks to the real files.

       This scheme has the advantage that if you update	the source,  you  need
       not  propagate the change to the	other architectures by hand, since all
       source in all shadow directories	are symlinks to	the real  thing:  just
       cd to the shadow	directory and recompile	away.

       The  todir  argument is optional	and defaults to	the current directory.
       The fromdir argument may	be relative (e.g., ../src) and is relative  to
       todir (not the current directory).

       Note  that  BitKeeper, CVS, CVS.adm, .git, .hg, RCS, SCCS, and .svn di-
       rectories are shadowed only if  the  -withrevinfo  flag	is  specified.
       Files with names	ending in ~ are	never shadowed.

       If  you	add files, simply run lndir again.  New	files will be silently
       added.  Old files will be checked that they have	the correct link.

       Deleting	files is a more	painful	problem; the symlinks will just	 point
       into never never	land.

       If  a file in fromdir is	a symbolic link, lndir will make the same link
       in todir	rather than making a link back to the (symbolic	link) entry in
       fromdir.	 The -ignorelinks flag changes this behavior.

	      Normally	lndir  outputs the name	of each	subdirectory as	it de-
	      scends into it.  The -silent option suppresses these status mes-

	      Causes  the  program to not treat	symbolic links in fromdir spe-
	      cially.  The link	created	in todir will point back to the	corre-
	      sponding	(symbolic  link) file in fromdir.  If the link is to a
	      directory, this is almost	certainly the wrong thing.

	      This option exists mostly	to emulate the behavior	the C  version
	      of lndir had in X11R6.  Its use is not recommended.

	      Causes  any  source  control manager subdirectories (those named
	      BitKeeper, CVS, CVS.adm, .git, .hg, RCS, SCCS, or	 .svn)	to  be
	      treated as any other directory, rather than ignored.

       The  program displays the name of each subdirectory it enters, followed
       by a colon.  The	-silent	option suppresses these	messages.

       A warning message is displayed if the symbolic link cannot be  created.
       The  usual  problem is that a regular file of the same name already ex-

       If the link already exists but doesn't point to the correct  file,  the
       program prints the link name and	the location where it does point.
