Legalisms
*********

  In general, each file has its own copyright notice stating the copying
permissions for that file.  Following is a summary.

  The Web2c system itself and most of the original WEB source files are
public domain.

  `tex.web', the MLTeX code, `mf.web', and `bibtex.web', are
copyrighted by their authors.  They may be copied verbatim, but may be
modified only through a `.ch' file.

  MetaPost-related files, including `mp.web' itself, are copyrighted
under X-like terms; the precise notice is included below.

  Finally, almost all of the Kpathsea library is covered by the GNU
Library General Public License, but part of one file is covered by the
regular GNU General Public License (*note Introduction:
(kpathsea)Introduction.).  Therefore, the _binaries_ resulting from a
standard Web2c compilation are also covered by the GPL; so if you
(re)distribute the binaries, you must also (offer to) distribute the
complete source that went into those binaries.  See the files `COPYING'
and `COPYING.LIB' for complete details on the GPL and LGPL.

  The following notice must be included by the terms of the MetaPost
copyright.

     Permission to use, copy, modify, and distribute this software and
     its documentation for any purpose and without fee is hereby
     granted, provided that the above copyright notice appear in all
     copies and that both that the copyright notice and this permission
     notice and warranty disclaimer appear in supporting documentation,
     and that the names of AT&T Bell Laboratories or any of its
     entities not be used in advertising or publicity pertaining to
     distribution of the software without specific, written prior
     permission.

     AT&T disclaims all warranties with regard to this software,
     including all implied warranties of merchantability and fitness.
     In no event shall AT&T be liable for any special, indirect or
     consequential damages or any damages whatsoever resulting from
     loss of use, data or profits, whether in an action of contract,
     negligence or other tortious action, arising out of or in
     connection with the use or performance of this software.
